I haven't tested this in Lucid, but if it doesn't work it should be possible to fix it with minor changes. There is a project based on the rootaufs script that seems to be up to date and perhaps easier to use but I haven't tried it yet: http://sourceforge.net/projects/lethe/files/

Thanks for the write-up, this is pretty cool!

Are there any updates for 10.04? I found that I needed to install grub2 in the chroot, since my laptop was using grub2… so grub-install was installing a version that was looking for a grub.cfg, not a menu.lst.

As far as aufs and the initrd scripts, has any of this been tested in lucid?

They do seem to have updated the rootaufs script for 9.10, the original is at the link below. https://help.ubuntu.com/community/aufsRootFileSystemOnUsbFlash#rootaufs%20Script

Hi Steve,
I found that the file rootaufs has problem applying to Karmic 9.10.
Lines #110 & #157 have different problems. Line #110: “modprobe -Qb” may be “modprobe -qb”. Line #157: should be a comment line (lack of a “#” sign).
Hence, I wondered that I still can install/remove some packages to the system even reboot.

You can install whatever you want, it just won’t be written to the USB stick and will be gone after a reboot, assuming you boot the read-only option.

I tried those read-only steps.
However after boot, grub menu shows 3 items, 1st is default.
I boot it from default. But I tried to install dhcp server, it can install.
Hence, what is your mean of read-only?
Thanks.

Hi,

Well, I had Ubuntu 8 (can’t remeber 8.4 or 8.10), but yesterday I reinstalled the whole system with ubuntu 9.10… and now the system boots fine. No idea what the problem was.

However, I have another problem. As soon as disconnected the display from the computer and restart the system, it hangs.
I already found out that there’s a problem with the kernel mode setting which should be deactivated via “nomodeset” kernel parameter in grub, but actually doesn’t work for me.

Unfortunately i can’t replicate that fsck error here, which version of Ubuntu are you using?

Hmm, never seen that before. When I get home tonight i’ll run through the entire tutorial again and see if i can replicate that error.

Oh man… I resolved this issue. When I typed ‘head rootaufs’ i saw, that there were some strange characters before #!, which were not displayed in VI or nano. Maybe this was a copy/paste mistake.

However, now the boot process stops when checking the root file system. I have this error:

fsck.ext2: No such device or address while trying to open /lib/init/rw/rootdev Possibly non-existent or swap device?
fsck died with exit status 8

I saw now that in this guide ext3 is used, but that should not be the problem?

thanks so far,
dd
