Sure, I have talked about the options and how the options are
evaluated.

Oh... sorry :-) Anyway, it's the same, the "-t" is usable without -a
too.
umount -a -t <type, ...>
the <type> is interpreted as pattern.
umount -t <type>
the <type> is filesystem type (so you can force umount to use for
example /sbin/umount.<type>).
The -O is usable with -a only.
