Summary: Is it safe now to use "mount -t nullfs" instead of mount_nullfs in makefiles (does it return non 0 values reliably on errors)?

I've stumbled upon the following comment in ports/Mk/bsd.commands.mk[1]:

> # XXX: this is a work-around for an obscure bug where
> # mount -t nullfs returns zero status on errors within
> # a make target

I cannot find a bug report for that. Is this comment still relevant after over 10 years?

trasz@, you've done some work recently on nullfs. Could it be related?
