sysvinit's mountpoint has that and i felt like keeping that part for the
other OS's just to be safe. I wouldn't object to removing it.

For the 'mountpoint /dev' case this would do, yes. But for the
-x and -d cases you'd have to also throw stat -c %t:%T and -c %d in
which is a bit cumbersome..

fwiw, debian uses it in it's bootup scripts. e.g.:
$ grep mountpoint /etc/init.d/*
/etc/init.d/checkroot.sh:			   mountpoint -q /dev
/etc/init.d/checkroot.sh:	ddev=`mountpoint -qx $rootdev`
/etc/init.d/checkroot.sh:	rdev=`mountpoint -d /`
/etc/init.d/checkroot.sh:		if [ "`mountpoint -qx
/dev/root`" = "4:0" ]
/etc/init.d/mountvirtfs:	if ! mountpoint -q $3
/etc/init.d/nfs-common:    if ! mountpoint -q "$2"
/etc/init.d/udev:  if mountpoint -q /dev/pts/; then
/etc/init.d/udev:  if mountpoint -q /dev/shm/; then
/etc/init.d/udev:      if mountpoint -q /dev/; then
/etc/init.d/udev:      if mountpoint -q /dev/; then
/etc/init.d/udev-mtab:if mountpoint -q $udev_root; then
/etc/init.d/udev-mtab:# mountpoint(1) does not report bind mounts
