Hi,
First of all, thanks for your quick reply...
I think Im using the latest version of AuFS which is available for my
Kernel, 2.6.29....
I've tried to do what you've just told me, but on the first line:
"mount -no remount,ro /"
it says: mount: / is busy
I've checked what you've told about the xino file, if I make this:
rocinante si_da74dd25 # cat /sys/fs/aufs/si_da74dd25/xi_path
/.rw/.aufs.xino
rocinante si_da74dd25 #
but, that file does not exist (although the patch should be fine):
rocinante si_da74dd25 # cat /.rw/.aufs.xino
cat: /.rw/.aufs.xino: No such file or directory
rocinante si_da74dd25 #
I think my problem is the way I make the chroot in the initRam, but im not
sure:
1) first I mount the two branches normally in /.ro and /.rw
2) then I make the union with aufs into /new_root
3) then, I move the previous /.ro and /.ro into /new_root/.ro and
/new_root/.rw with "mount --move"
4) then I make a normal chroot
In your aufsRoot script I see you are making the union not by the full root
but specifying separately each /tmp /bin..... It only make sense for me if
I'd want to exclude any folder, could be it related with my problem. Is my
procedure right?
Thanks

First, your aufs version is obsoleted and not maintained now.
Second, I'd suggest you to read the aufs manual.
(from the aufs manual)
----------------------------------------------------------------------
When your aufs is the root directory of your system, and your system
tells you some of the filesystem were not unmounted cleanly, try these
procedure when you shutdown your system.
.nf
# mount -no remount,ro /
# for i in $writable_branches
# do mount -no remount,ro $i
# done
.fi
If your xino file is on a hard drive, you also need to specify
`noxino' option or `xino=/your/tmpfs/xino' at remounting root
directory.
----------------------------------------------------------------------
I guess XINO file makes your .rw busy.
