Hm.  It is not enough to have /etc/mtab writable (I tried).  Mount
will try to create /etc/mtab~, and this require /etc/ to be writable
too.  mtab~ can not be a symlink to a writable area (I tried this
too), nor can it be a bind-mount because it is used as a lock to make
sure only one mount command is running.

What about modifying the mount command to be able to write its files
to /var/run/ or /var/lock/ instead?

Good point.

Happy hacking,
