Hello again, I made some further tests and at least with UnionFS 2.5.1 (which is in trunk) the shutdown does the remount in read-only mode of /dev/hda2 (unionfs) properly. No issues here.
I can't speak for UnionFS 2.4 (which is used by Astlinux 0.6). So, doing the little check as I advised in my previous e-mail does not harm. How are your filesystems mounted? Maybe you can give us a "mount" output? (just trying to help to track down the problem....)
