BusyBox Error

Im working with Andrizoid atm at seeing if we can get some progress on his Ubuntu project. Heres the issue.
Code:
busybox mount -o --bind ./dev/pts /data/local/ubuntu/dev/pts
mount: cannot read /etc/fstab: No such file or directory
In doing a little research I came across this
If there is no entry for /dev/fd0 in my fstab when I issue the command above, mount gets very confused because it doesn't know where to mount the floppy.

This come from http://www.tuxfiles.org/linuxhelp/fstab.html which gives a quick breakdown of what the etc/fstab file is. When i went exploring I couldnt find an etc/fstab
Code:
[B]
mount: cannot read /etc/fstab: No such file or directory
[/B]
The thing about Android though...there IS NO /ETC/FSTAB file because its become obsolete.
The init program directly mounts all filesystems and devices using either hard-coded file names or device names generated by probing the sysfs filesystem (thereby eliminating the need for a /etc/fstab file in Android). After device/system files are mounted, init reads /etc/init.rc and invokes the programs listed there (one of the first of which is the console shell).

EDIT: Conclusion
After bouncing some ideas around, I've come to the conclusion that it HAS to be a Busybox issue.
An Android specific variation of Busybox should take into account the fact that there isnt an etc/fstab file. The fact that these commands work on other phones leads me to think that its an Eris specific issue. If anyone remembers there were issues when using the Busybox available on the market on the Eris.
Looks like we need a Busybox update

Modify the mount command.
If the version of BusyBox is the Android version, report this issue (as a bug?). If it's the standard Linux BusyBox, the devs may not be interested. Or, if BusyBox is just calling the standard mount command, then it's not a BusyBox issue for them to worry about.

I'm using the Android Busybox, and those commands are being executed in an adb shell so I doubt that its calling the standard mount command-it should be calling the (hopefully) Android specific mount command. The things thats confusing me is that those same commands worked just fine for other phones. I dont see why I would get an error and others would have no issue with it?
EDIT:
And if you ave any recommendations for what I should modify the mount command to, let me know.

You mention a reference to /dev/fd0 but I'm 99.9% that's referring to the *nix mount command. The Android/BusyBox version should know better than to look for a floppy drive.
Where is BusyBox maintained ?
I did find a page about an Android ROM from Nov 2008 that mentions
- changed the "mount" symlink to be busybox's mount instead of toolbox's mount
- added an /etc/fstab file that busybox's mount can use, that lists the standard system partitions.

Is "mount" in fact an internal adb command ?

The floppy drive reference was just from some background info I pulled on the etc/fstab file. I wasnt actually trying to mount a floppy disk
I have no idea where I would put in a bug report or anything. I know Stericson was the publisher of the BusyBox app thats avaiable on the market, but the one for the Eris is different anyways so idk if he could help.
Im not sure what you mean by your last statement, but mount is not a command that you can use in a shell on its own. You have to use busybox mount ...
If you can show me where you found that rom from I may be able to finish this. I was just talking to a buddy of mine about making my own /etc/fstab and slipping it in just so that the mount command would work. If theres already one put together then thats way less work for me

What I meant by referring to that info you found was that person couldn't have been talking about the Android version. I didn't think you were trying to mount a floppy.
You sure that there's no "adb mount" ? Look here, http://forum.xda-developers.com/showthread.php?t=517874. They refer to "adb shell mount".
Personally, I would just create an /etc/fstab file (I believe it can be empty) and see what happens.

well ive got an /ect/fstab file that i took from here http://www.android-devs.com/?p=152
Code:
# /etc/fstab: static file system information
#
# file system mount point type options dump pass
/dev/block/mmcblk0p2 / ext2 defaults 1 1
proc /proc proc defaults 0 0
/dev/mmcblk0p1 /media/sdcard vfat defaults 0 0
But thats from a guide about debian on the N1 and the way they are doing it is much different from the method I'm using.
adb shell mount give the error that mount isnt found. it has to be called through busybox-at least in the instance that im using it in
Code:
busybox mount -o --bind /dev/pts /data/local/ubuntu/dev/pts

Any fix for this? (Picture attached)

I'm out of ideas. I've asked before but got no where. I figured a picture may help. I can root and get all the way to cm 7.0.3 but anything 1.2 update related fails. I've tried using the cwm flashable update but that fails too.
The pic is from a fresh 1.0. (I've tried 1.1 also.)

USE THIS http://forum.xda-developers.com/showthread.php?t=1000957 with a sandisk 8 gb class 4 chip.....
Call it a day.... use CM7.1 RC, its very stable.... if you need to update to nightlies, its simple as just copy the downloaded file onto the external memory card.

Yeah that is a last resort. I plan on giving that nook to my brother who is android illiterate. How did everything get borked anyway?
I bypassed the registration and my nook info looks like this

OH CRAP.... looks like some sort of internal corruption....
Do a complete wipe......
THEN Do the SDCard install...
It's seemless to the user... THere is no bootup screen or anything... The nook will automatically boot to the sd first.... so he won't need to know anything...
if he is REALLY not too literate, then he can just pull the sd, and it boots into the nook.

Ok....I'm not sure what kind of SD card I have... it just says micro SD hc 4gb with a circle with a 4 in it.
So I'm assuming its a class 4 SD card...not sure the brand though

Looks like your "ROM" got corrupted... it is a partition (/dev/mmcblk0p2) that is mounted r/w as /rom
Check and see if you have partition mmcblk0p3 and if rombackup.zip is in there...
Boot off CWM bootable uSD... then try the following:
adb shell mkdir /tmp
adb shell mount /dev/block/mmcblk0p3 /tmp
adb shell ls /tmp
if rombackup.zip is there... you're fine... we can fix it.

Wow I've been rooting for about 3 years and have never ever used adb. Crazy right? Can anybody point me in the right direction ?

can that be done in terminal emulator or do I gotta go and install adb and whatever else on my computer?

term emulator would work.

Ok I tried adb shell mkdir /tmp and i get mkdir: cant create directory /tmp: read only file system.
Tried adb shell mount /dev/block/mmcblk0p3 /tmp, it fails and says no such file or directory.
does this mean if I want the newest versions of cm7 I gotta do it off sd?

Arrrgh been trying all night. I hope there's still a way and its not completely borked

You could still run CM7 off of EMMC... we're just trying to salvage your device specific information if there's any hope... which I truly think there is.

Sorry... was at work... didn't have a chance to reply...
try adb remount
before the other steps above... if you get an error then you will need to
adb shell mount -o remount,rw /dev/block/mmcblk0p5 /system
One of those two should work from CWM bootable uSD... then the steps I listed above will work... IF you have the rombackup.zip file... we'll help you through fixing your issues.

I got the same error messages after the remount but the "adb shell mount -o remount,rw /dev/block/mmcblk0p5 /system" seemed liked it work. it didnt say anything though

It won't give you a message saying it was successful... just try the other commands to see if you have backuprom.zip on partition 3. If its there... we can fix the issues... if not.. we have to make stuff up to fix it
You can do the same thing for partition 2 (where the device specific stuff is stored unzipped) by creating directory called tmp2 and mounting /dev/block/mmcblk0p2 to it... in that one 3 specific files you're looking for are:
DeviceID
MACAddress
SerialNumber
Those are plain text type files (but not DOS or windows formatted.. so you can view them, but don't edit them in notepad)

Ok you are gonna have to help me with that. I wouldnt even know where to begin. We all gotta push our limits right? haha

Check your PM... give me a call if you want.
I gave you some bad commands.... this should work:
adb shell mount -O remount /remount, rw /dev/block/mmcblk0p5 /system
adb shell mkdir /system/tmp
adb shell mount /dev/block/mmcblk0p3 /system/tmp
adb shell ls -l /system/tmp
then
adb shell mkdir /system/tmp2
adb shell mount /dev/block/mmcblk0p2 /system/tmp2
adb shell ls -l /system/tmp2
OR
adb shell
mkdir /system/tmp
etc.
etc.
Since you have the rombackup.zip on mmcblk0p3 try this...
extract attached file... then run the resettofactory.cmd file... it will copy the BootCnt file to /rom and make it think its on 8th failed boot.

How do I convert rfs to ext2 or ext4 MANUALLY?

How do I convert partitions manually? What are the commands or procedures without using software?

If you have fugumod or g3mod kernel you can put a fs.convert in their respective folders.
Just make a file with notepad and write for example:
stl6 ext4
And save it without .txt extension and put in /sdcard/Android/data/fugumod (if you use fugumod) or sdcard/Android/g3mod (if you use fugumod)
Remember:
stl6 is system
stl7 is data
stl8 is cache
ale_bot from xda app

I said I wanted to know the manual method But thanks for you willing to help!
Because I have another Android phone as well and I want to make a universal file system conversion application... To make life easier for every Android owner.
I was hoping someone could tell me everything I needed...

For that u'll need the kernel to support the fs so it cant be universal
also the manual way is different in different devices
P.S. : This ain't development, ask your questions in general or q/a

Please notice that even if you do convert manually, kernel is still supposed to support ext2/4 file system. Stock kernel does not support it, so in some way you have always to take in consideration which kernel you are running.

My kernel supports ext2
All I need is now some scripts...
for example /dev/stl12 is /system

I think "universal" is not so easy possible as you would like. Every device has another hardware and so the OS (although it's android) is not the same...
On Galaxy 3 the /system parition is /dev/stl6... not stl12
There is the app G3mod by Dympy / Dharam.
The "manual" way is advised here for you (convert.fs - file)
both ways only work on G3 with fugmod or G3mod-kernel...
If you wanna make your own "universal" app you need to do it the linux-way with mkfs -t ext?? /dev/stl??
with manual commands or within a script (maybe with cases --> "universal") in adb shell during CWM or script at booting, as the filesystems must not be mounted while converting!
However you won't be coming around learning to handle linux!

So I can do this?
su
mount -o remount,rw /dev/stl12 /system
busybox cp /system/* /sdcard/system_backup/
reboot recovery
Click to expand...
Click to collapse
# Now we are in CWM and we unmount /system manually (unless someone gives me the command I can replace this with the command to unmount /system???)
mkfs -t ext2 /dev/stl12
mount -o remount,rw /dev/stl12 /system
busybox cp /sdcard/system_backup/* /system/*
chmod 644 /system/*
sync
reboot
Click to expand...
Click to collapse
Do you think this process would work??? OR do I need to do something more? I believe ALL my commands are correct. Can I proceed or do I have to declare something somewhere so Android knows it's ext2 or is this fine ?

I hope this is ok ? I am going to try it out in two hours...

I tried it to convert it to ext2...
The conversion went succesfull
But after reboot it detects any partition I convert to ext2 as ext4... But ext4 is not supported :/ WTF?
Should I try mke2fs instead?

Ubuntu 11.04 unity-2d VNC

Hi guys,
I'm really new here, I can't post in this thread: http://forum.xda-developers.com/showthread.php?t=836022
I created a working ubuntu11.04 .img, with unity-2d. I don't know if anybody cares, it was funny to make.
It is just a minimal install with unity-2d and tightvncserver. Really minimal. Firefox, office applications, anything else DOES NOT installed.
However, you can install anything using apt-get install.
I installed wget and nano, because it was needed to configure the vnc. I plan to make a bigger one with all the programs and stuff installed. Maybe tomorrow. Or next week.
How to use: Unzip, rename to ubuntu.img and simply replace the original ubuntu.img with this one. Use root as user/nickname and ubuntu as password, as usual.
Download link to .img:
Download link to the other files needed:
Links tomorrow. "New" .img too.

-Sorry for my english.
Please help! Give me additional space by using my referral: http://db.tt/W0knUea
edit1: So, now I've got 10 comments, I don't have to write everything in separate comments. What I've done yet: make some simple script to automatically turn on/off the vncserver (1024x600, tab native res, I found it enough), and get tired of the resource hungriness of unity-2d. I mean it needs about the same CPU power (I guess) as the galaxy tab has, and it needs about 200MB RAM. But this is to run native. The VNC version is far from native, so it's slow as f..., I mean, very slow. Then I looked for a little less resource-hungry desktop environment, and I found lxde. I made an image with that. It's slow too, but much faster than unity-2d. I need to configure it a little more, to be more touch-friendly. And I want to do a few other thing, and write a how to make your own .img file thing. If you want to do it now, here some links, I will write about it sometimes.

I also suggest reading mount, umount and rootstock man pages.

This image works quite well. As with every VNC build, its a bit slow and Unity doesn't help that (even in its nice Unity-2d form), but if you want Ubuntu on your Tab this is a pretty sweet image. Ultra-lightweight, too. Nice work, OP!

Hi!
The SDK is not strictly necessary since you could use a Terminal Emulator to run the necessary commands but using an ADB shell is just bit easier sometimes. That being said, you should install the SDK if you ever want to do much with an Android. It's easy to install and very powerful.
And yes, write bootubuntu instead of bootlinux when prompted. I know what you mean

Allright, I went through it and now got it installed . But I can't see firefox nor any office application... How to access them? Also can't get into terminal to write 'apt-install' there.....

I'll write a howto tonight or next day or I don't know. I need to study to university too. You need adb or android terminal emulator (from the market) to use apt. Short version: when your prompt is "[email protected]:/#" simply do this command: "apt-get install firefox"

Just poked around a little. Now I know (or at least I think I now) what else I have to do.
http://dl.dropbox.com/u/41806444/bootubuntu2
Cleaned up version of bootubuntu. Copy it to /sdcard/ubuntu and simply run it. You need to use the sh command, so type "sh bootubuntu2" in android terminal emulator or adb shell in /sdcard/ubuntu foler.

Oh, sorry I forgot to mention, this script only works with overcome kernel and rom. You shold modify the
mount -o remount,rw -t ext4 /dev/block/stl9 /system
and the
mount -o remount,ro -t ext4 /dev/block/stl9 /system
rows. Enter "mount" to android terminal to see your /system dir type and path.

Synaptic looks like to work, software-center doesn't even start.

To really enjoy full linux distros like this, one should have a swap-enabled kernel. Instead, kernel on the Tab has no swap, and if you dare open some large app, the lack of ram makes it slow and unresponsive.
This is the main problem imho.

[Q] mount -o bind on Android 4.2

Hi,
I was using Gscript with a mount script to bind my Gameloft game data folders on external USB disk to the original place on the internal SD card.
a sample script is like:
Code:
mount -o bind /storage/usbdisk/N7/Android/Data/com.gameloft.android.ANMP.GloftN3HM /sdcard/Android/data/com.gameloft.android.ANMP.GloftN3HM
However, after updating to Android 4.2, I lost this capability. The mounts are only available within the context of the app that I mount.
When I leave the app (Gscript), and open a terminal emulator, I see the mount (binding) is gone.
Is there a solution to this on Android 4.2 ?
Thanks.

Anybody who can help with this ?
thx.

This should be the same solution as with cifs and others...

good question,i opened a similar 3ad in past days but no reply..HEREgscripts system and directory bind aren't working anymore..i think it's the changed mount points or how android manage them..

vorcers,
thanks for this information. But what do you mean by 'Stickmount writes the shell-commands in "/system/bin/debuggerd"' ?
/system/bin/debuggerd seems to be a binary file. How can we write shell commands in it ?
Thanks.
