I tried with just that fstab and it's still bearable. I have attached
the more complete fstab with all my bind mounts. This ends up with ~2500
lines in the output of the mount command... For instance
proc on
/usr/local/montesting/home/wheezy-32/home/wheezy/home/squeeze-32/home/squeeze/home/32/home/32/proc
type proc (rw,relatime)
There is no reason why it should contain such recursive mounts...
Just to save you the time, here are the commands to create the bind
mount directories:
mkdir -p /home/usr/src
mkdir -p /var/cache/pbuilder
mkdir -p /home/pbuilder
mkdir -p /home/tmp
for i in 32 unstable squeeze squeeze-32 wheezy wheezy-32 ; do
mkdir -p /home/$i/dev
mkdir -p /home/$i/proc
mkdir -p /home/$i/sys
mkdir -p /home/$i/home
mkdir -p /home/$i/usr/src
mkdir -p /home/$i/tmp
mkdir -p /home/$i/var/cache/pbuilder/result
done
mkdir -p /usr/local/montesting/home
