This is my first post here, but I figured I'd share this since doesn't appear to have been done yet.
As I'm sure most of you know the locked bootloader introduces challenges to getting your favo(u)rite flavo(u)r of linux on to the Droid 2.
I expect that you have rooted your phone and have busybox installed/working...
Normally when one wants to do this they get a linux image file and mount it as a loop device and then chroot to it's mounted folder. Because one can create a loop device but can't mount it.
My solution has been a "simple" one but may not have been tried:
Extract the contents of the image on a separate system and then push everything to /data/local/mnt.
For instance I set up a loop device on Ubuntu:
losetup /dev/loop0 /home/usernamehere/distributionnamehere.img
mount -t ext2 /dev/loop0 /home/usernamehere/somemountfoldername
Then I remove security stuff:
sudo chmod 777 /home/usernamehere/somemountfoldername
sudo adb shell
chmod 777 /data/local/mnt
exit
sudo adb push /home/usernamehere/somemountfoldername /data/local/mnt
(Wait for the push to happen stop it when you see X11/X11/X11/X11 or remove that symbolic link before pushing. If you stop it you'll have to push the other folders separately)
After it's done the bootubuntu which points to that /data/local/mnt share (or /data/local/ubuntu or /data/local/debian or whatever) should throw a few errors about mounting which is expected because we haven't fixed the fact that loop devices aren't mountable, but since we pushed the files to the 'mount' directory, the script finds it anyways and chroots to the /data/local/mnt and runs /data/local/mnt/bin/bash (or /bin/bash from the chroot point of view.)
This will get you to the root prompt.
I'm still working on getting the bash: groups: message to go away, but I think that is just that I didn't get everything copied initially.
Also I have yet to finish setting up VNC.
Anyway I hope this helps some people out.
I may do a script or more complete instructions later if requested.
Thanks,
Sky Adams
Thanks, I've been stumped by this for awhile. Your method allowed me to push the files but my script still doesn't find it. I'm going to need you to post your bootubuntu script. I have an image from androidclone.com that has vnc setup already, just need to get it to execute.
Confirmed working on rooted Droid X. Used Lakia image from androidclone dot com
1) Partitioned 16GB SD: Shrink to 11.9 GB leaving ~4GB. Then create new ext3 partition in free space
2) mount ext3 partition and create the loop to the image as skrull mentioned above.
3) then just "[email protected]# cp -r pathtoloopiface/* pathto4gbmount/"
4) takes a while but preserves the symlinks to avoid the X11/X11/X11/ issue above. (I think the reason you were having problems with the bash at the end, was an incomplete adb transfer of the /usr folder and probably no /var transfer at all. At least that was the case when I tried.)
5) push and chmod 777 this bootubuntu script to /system/bin:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system
export kit=/sdcard/ubuntu
export bin=/system/bin
export mnt=/data/local/mnt
export PATH=$bin:/usr/bin:/usr/sbin:/bin:$PATH
export TERM=linux
export HOME=/root
mount -t ext3 /dev/block/mmcblk0p2 $mnt
mount -t devpts devpts $mnt/dev/pts
mount -t proc proc $mnt/proc
mount -t sysfs sysfs $mnt/sys
sysctl -w net.ipv4.ip_forward=1
echo "Setting /etc/resolv.conf to Google Open DNS 8.8.8.8 and 8.8.4.4"
echo "nameserver 8.8.8.8" > $mnt/etc/resolv.conf
echo "nameserver 8.8.4.4" >> $mnt/etc/resolv.conf
echo "Setting localhost on /etc/hosts "
echo "127.0.0.1 localhost" > $mnt/etc/hosts
echo "READY TO ROCK AND ROLL BABY! "
echo "Brought to you by NexusOneHacks.net and the open source community! "
echo " "

echo "Ubuntu 10.10 - Laika Edition by Androidclone.com "
echo "Website:http : / /www . androidclone . com"
echo "Email:[email protected] . com"
chroot $mnt /bin/bash
#After exit command is executed clear it all up
echo " "
echo "Shutting down Ubuntu"
umount $mnt/dev/pts
umount $mnt/proc
umount $mnt/sys
# the fuser command below allows us to kill all processes using the mount.
# otherwise umount will fail and the vnc session will still be alive.
# if it fails just run the fuser and umount again manualy.
fuser -k $mnt
umount $mnt
6) make sure there is a path to /data/local/mnt on the device and just run 'bootubuntu' from a root shell. you should get: "[email protected]/#:"
7) read the site on androidclone dot com for details on logging into the already running vnc service for a full LXDE session.
8) happy hacking.
D2G
any idea if this could free up the bootloader for the D2G allowing us to modify radio?
No, this will not circumvent the bootloader to load custom kernels. But who cares. many of the things we want, added features etc., can be loaded up in the form of kernel modules. I am not proficient enough to be able to compile my own modules yet but i'm working on a few things.
Radio
Can a kernal module be used to change the radio?
Good share, thank you very much.
ARGH!
I have probably spent 8 to 10 hours trying to get Ubuntu to boot. It seems that I cannot mount the path it wants to mount.
I can as it would seem to do this in shell it self, but still have some errors.
Do you think if I SBF my Droid X then root it - then follow the directions this would work. I am at an end now...and frustrated

Anyone tried to do that on our SGS2?
I've did this already on my Hero and on my Desire... I have no time right now, but I will try to get it running.
I'm sure it will be super fast...
Edit:
http://galaxytabhacks.com/galaxy-ta...tall-ubuntu-linux-on-galaxy-tab-10-1-tabuntu/
They already did it on the Galaxy Tab. It's time to get it running on the SGS2!
Tried it and the LXDE image is working... very fast.
I can open the file manager and everything expect the Browser... also installed firefox but couldn't run it! I get the error:
Xlib: extension “RANDR” missing on display “:1.0″.
I think this has something to do with VNC... will try to reinstall tightvnc and see if it helps.
I'm surprised that nobody is interested in this...
I'd look at it at some point, other than the fact O2 cannot organise themselves to send out my SGS2.
I think a lot of people are still waiting on phones to arrive...

pulser_g2, I think it's time to get that chroot working! I've tried again with another build with no luck. I think we need a special kernel... back when I had my desire I remember that it worked only with very few custom kernels.. because they had some parameter enabled but I can't remember which!
Under this link you can see people did the same on the Galaxy Tab 10.1:
http://galaxytabhacks.com/galaxy-ta...tall-ubuntu-linux-on-galaxy-tab-10-1-tabuntu/
On our SGS2 it would be epic... when we get it working we can just connect via VNC from our desktops to our SGS2 and use it as a PC!! Or via the viewer on the SGS2 itself... screen is big enough.
I hope someone can move this thread to the DEV forum so we can start working on it.
I started to work on running Ubuntu 11.04 on the SGSII yesterday, from scratch as I didn't find an existing way to do it. As I may need some kernel modules, I'm creating a virtualbox environment to cross-compile them.
I managed to run Ubuntu some time ago on my Xperia X10 so I already have some background on the subject so it might not take months to have it working.
I got debian running in chroot and managed to get xfce going. Not real useful at the moment but at least it works.
I just had to root the phone and followed the guide at saurik.com

Just got Ubuntu 10 running on my S2, loop device and ext4 is supported by the default kernel !
Hmm, strange... do you have root? I'm on VillainROM 1.4 with latest CF-ROOT and it doesn't work exactly because of loop devices!

I'm using an insecure kernel with default firmware.
For loop device, you need to 'losetup /dev/block/loop0 /path_to_image' and not using /dev/loop0 (returned by default by losetup but this is wrong)
and after that 'mount -t ext4 /dev/block/loop0 /my_mount_dir'
ext4 is supporting ext2/ext3 too

mknod is useless in your script, as loop device is already created.

type :
losetup /dev/block/loop0 /sdcard/ubuntu/ubuntu.img
mount -t ext4 /dev/block/loop0 /data/local/mnt
(replace ubuntu.img and /data/local/mnt with your current image/dir)
if '/data/local/mnt' is empty then your image is broken.
Also type 'dmesg' to check why it's broken.
extract zip to sdcard
run 'sh /sdcard/debian/install.sh' to copy the script to /system/xbin
'debianboot' to enter chroot
the prompt will change to debian if everything goes well

Using the HD2 port as basis, I got Ubuntu 11.04 running on our Galaxy SII :
Some applications don't run in the menus but most of them are ok (Firefox 5 at first!).
As Unity requires hardware acceleration, I was unable to enable it for now.
As usual VNC is needed, so it's not very smooth to use, but it seems to me that 11.04 is smoother than 10.10 on my device.

# chmod 744 /system/etc/install-recovery.sh
# mount -o ro,remount -t ext3 /dev/block/mmcblk1p21 /system
Wow, Froyo... Been a while...
I am trying to:
* run backtrack image on my slide the small custom smaller image not the +4gig one for fat32
* get RW to /system for su updated and allow rootkeeper to 'work' http://forum.xda-developers.com/showthread.php?p=21219704
* I seen several tutorials but I am not sure what one to follow .. i have S-ON and I assume I need that off for su to update within clockwork etc ... none of the other root apps work.. the superuser.apk is installed and I allow perms but nothing seems to work.. I am hoping it is a easy fix ..

I readed that ext2 and chroot not working could come from the 4.3 but I'm not sure about this information.
I readed that most of custom ROM handle this.
