Hi,

Regarding the "aufs mount" problem that I reported on Sun, 5 Oct 2008
in gmane.linux.distributions.grml.user, I found that the solution is
not yet in aufs-modules yet.

As per
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=501184

,-----
| the bug you reported is fixed in the latest version of
| aufs
|
|    * Install mount.aufs and umount.aufs in /sbin (Closes: #501184)
`-----

however, I didn't find any mount.aufs executable in PATH, neither
/usr/sbin/mount.aufs nor /sbin/mount.aufs , tested under
grml64-medium_lenny_20090315.iso :

cd /dev/shm
mkdir -pv aufs/day{0,1} aufs/base aufs/u
mount -v -t aufs -o br:aufs/day0:aufs/base none aufs/u
mount -v -o remount,prepend:aufs/day1,mod:aufs/day0=ro,del:aufs/day0 aufs/u

-- day0 show up 3 times.

umount -v aufs/u

$ dpkg -l | grep aufs
