Sean Eric Fagan ba7a55d934 Add two options to allow mount to avoid covering up existing mount points. ... The two options are * nocover/cover: Prevent/allow mounting over an existing root mountpoint. E.g., "mount -t ufs -o nocover /dev/sd1a /usr/local" will fail if /usr/local is already a mountpoint. * emptydir/noemptydir: Prevent/allow mounting on a non-empty directory. E.g., "mount -t ufs -o emptydir /dev/sd1a /usr" will fail. Neither of these options is intended to be a default, for historical and compatibility reasons.
