Link /proc/mounts to /etc/mtab.

During system start, the /etc/init/mountall.conf on Ubuntu is unable to
generate the /etc/mtab file from the /proc/mounts file if a ZFS filesystem is
already mounted.

However, mountall 2.18 behaves properly if /etc/mtab is a symlink to
/proc/mounts.  This version was first published in Ubuntu Maverick.

Additionally, the mountall package is peculiar to Ubuntu, so the mountall
dependency breaks Debian compatibility.  A better solution would be to update
mountall to recognize ZFS mounts, or to find a proc syntax that mountall
already recognizes.
