Doesn't place filesystem type in /etc/mtab

[Scott James Remnant (Canonical)]

At least when using XFS, the filesystem type doesn't end up in /etc/mtab,
instead you get "unknown", e.g.:

/dev/hda2 / unknown rw 0 0

I traced this to /etc/init.d/checkroot.sh, specifically this bit that adds the
mtab entry:

if [ "$init_mtab" = yes ]
then
        [ "$roottype" != none ] && mount -f -o $rootopts $fstabroot /
        [ -n "$devfs" ] && mount -f $devfs
        . /etc/init.d/mountvirtfs
fi

It needs '-t $roottype' added before the '$fstabroot' bit ... that way mount
knows what file system type to add to mtab.

Although this seems superficial, it's actually quite important as without this
information laptop-mode doesn't know how to adjust the filesystem settings and
set the "noatime" bit (ie. you get a non-slumbering drive).
