Can somebody please explain the difference between these two commands.
1) mount -o remount,rw -t yaffs2 /dev/block/mtdblock4 /system
2) mount -o rw,remount -t ext3 /dev/block/mmcblk1p21 /system
In adb I'm using the latter to mount my system dir as rw. I perform what I have to then issue the next command:
mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
But it tells me the device is busy and to try again later. Well it never lets me remount as ro so I just exit, perform a reboot of the phone, and it is back to ro. I can't help think this is not a good way of doing it though. So I was gonna try this other command but don't know what exactly either is or the difference between the two. Anyway some help would be greatly appreciated.
***EDIT***
OK I finally got it to work. Seems you can not enter adb, root, exit adb, then enter adb again, attempt to unroot. The unroot takes and all works until I try to remount as ro, then I get above problem. Now when I root, exit adb, reboot phone, re-enter adb, and attempt to unroot everthing goes as expected with remounting as ro.
So thanks for anybody that at least took a look at the thread. Seems I have it squashed though. If you are wondering I'm testing some things out that is why I'm rooting, and unrooting back to back.
I don't even bother remounting. I just type #reboot. It will remount, by default, when the system starts up.

Yeah that's what I had to resort to, but as I stated. I just can't help think that's not a good practice to get into.
Anyway I found what was causing my trouble and remounting as ro with the previous command works fine.

To answer your question about the difference in the two commands... The yaffs2 or ext3 is the specifying the you're off file system you are mounting as.

Thanks for the response. Could you explain in more detail. I don't understand what you mean. Again thank you for taking time with such a noob thing.

mount command line options...
"-t <option>"
"t" stands for "type" and <option> = the linux filesystem type. Linux supports many. "yaffs" = "yet another flash file system" (lot's of tongue-in-cheek developers work on linux). "yaffs2" is v2 of this type of file system.
ext3 is a widely used linux file system.
essentially, the filesystem type tells linux how the data is actually organized on the disk.
the /dev/... that follows is the raw device to associate the filesystem type with.
So I take it that the phone or more directly adb can handle either file system? What of the mtdblock4 and mmcblk1p21 entries? I guess i just don't understand how two so different commands can mount/unmount the same folder. Again thank you very much for your time.

well, adb is just a way to open a terminal session on your phone. Think of it like opening a command prompt on windows. So it is the linux OS on your DX that is processing (handling) the command.
The two commands mount different raw devices (that actually are formatted with different filesystems) to the same "/system" mountpoint. In linux, a mountpoint is kind of like a drive letter would be in dos. What's cool about linux is that you can mount a raw device anywhere in the filesystem tree (where the root is specifiied as "/"). Windows provides that same functionality now with it's ability to map devices to folders.
I believe I'm beginning to wrap my head around it. Been fool'n w/ computer for awhile. I really have no excuse to be so illiterate on linux. I really need to just dig in. Any suggested starting points? I really loved dos and miss it so. lol. So I'm thinking I will probably enjoy linux more.

I couldn't find any threads on this, sorry if it's been asked before.
I can mount CIFS/NFS shares fine through CIFS Manager, but it doesn't auto-mount those shares on boot.
I'm trying to find a way to do this on boot. I can't find any sort of fstab from looking around that I could use for this.
I find some information that suggested that you can run script commands on boot if they're located at /data/local/userinit.sh So I attempted to put the mount commands in there.
userinit.sh said:
#!/system/bin/sh
mount -t cifs //192.168.1.147/comics /mnt/cifs/comics -o user="joe"
mount -t cifs "//192.168.1.147/collen's movies" /mnt/cifs/avis -o user="joe"
Click to expand...
Click to collapse
(yeah, I know "collen" is misspelled, but it is on the share)
both those commands *will* mount when I do them from terminal after creating the /mnt/cifs/comics and /mnt/cifs/avis directories... For some reason though, they get removed on each boot... so I suspect that maybe that's preventing the script from mounting them?
Anyone know of a way to do this?
You might try adding:
mkdir -p /mnt/cifs/comics
mkdir -p /mnt/cifs/avis
to the script before the mount commands, to make sure the mount points are there after a reboot. It might also be that the userinit.sh script is not being run as the superuser, which may be necessary for the mount command to work.
Actually, it occurs to me that I'm a bit of an idiot for thinking this would work...
I doubt it would have a wifi connection when any boot scripts get ran... so a CIFS mount shouldn't work at that point anyway.
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:

Links tomorrow. "New" .img too.

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!
Firstly, thankyou for not making 10 spam posts just to get this posted in the Development section, shouldnt take you long to get 10 posts under your belt in this thread then I'll move it into the dev section for you
Good job by the way..
how to run this?

It's writen down here.
The link to the files is in the first post.
Do I write 'bootubuntu' in command line instead of 'bootlinux' or do I have to change the filename of 'bootubuntu' file? I guess first of the two is correct, but it's better to ask than to brick
Oh and is the AndroidSDK really needed? I don't see anything about usage of it in instruction....

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.

Currently I'm using this cmd through adb each time I restart my FireTV "mount -o noperm,unc=........."
to mount my shares from my NAS locally on XBMC
I saw a method that uses system/etc/install-recovery.sh
to create a mounting point at boot time but I can't find that file at that location
and Idk if I can just adb push to create it and that's it, it would be called at boot
If someone with more experience could help me on this I would really appreciate it
Just create and chmod 755
