thats how we do it since day one (a grep -r in the plugin dir helps a
lot):

ogra/ceron:~/devel/hardy-ltsp/ltsp-trunk$ cat server/plugins/ltsp-build-client/Ubuntu/010-etc-mtab
case "$MODE" in
    after-install)
        # divert /etc/mtab and point it to /proc/mounts
        chroot $ROOT dpkg-divert --package ltsp-client --add --rename \
                                 --divert /etc/mtab.real /etc/mtab
        chroot $ROOT ln -sf /proc/mounts /etc/mtab
        ;;
esac

the divert moves the file out of the way (in case a package will claim
it dpkg-divert makes sure such a package doesnt touch it (i.e. on
updates)) and then we simply link /proc/mounts to be mtab. mind you, if
you have apps that actually rely on the format of mtab which is slightly
different to /proc/mounts you are screwed (we dont have such apps in the
client chroots usually, but if you ever want to run something like gvfs
on a client, which apparently massively relies on such things like
fstab, mtab etc, then you will run into probs)
