OK, so if I make a forward map and add to it reverse maps for every
non-bind-mounted filesystem visible from the current root, then
mount-point crossing into those filesystems should work?
Let's see:
unionimap -c /tmp/maps/a.map
for name in $(awk '{print $2}' < /proc/mounts | sort -u); do
[[ "$(df -aPT $name | tail -1 | awk '{print $2;}')" == "none" ]] && continue
mapname=$name
[[ "$mapname" == "/" ]] && mapname=/root
unionimap -a /tmp/maps/a.map /tmp/maps/$(echo $mapname | tr "/" "-" | cut
-c2-).map $name
done
mount -t unionfs -o dirs=/tmp/foo=rw:/=ro,imap=$(echo /tmp/maps/*.map | tr " "
":") none /tmp/unionfs
amaterasu:/# ls -l /tmp/unionfs/usr
total 0
Nope, no sign of mount-point-crossing yet.
What am I doing wrong?
