Yes.  Though we don't use the same mount/umount command, most basic flags are
the same.

     -f      The file system is forcibly unmounted.  Active special devices
             continue to work, but all other files return errors if further
             accesses are attempted.  The root file system cannot be forcibly
             unmounted.

     -f      Forces the revocation of write access when trying to downgrade a
             file system mount status from read-write to read-only.  Also
             forces the R/W mount of an unclean file system (dangerous; use
             with caution).
