>Description:
When trying to use the remount_optional option on a nanobsd like build that was
going to run from an iso image with an optional remount of /dev/ufs/cfg onto
/conf/default/etc I discovered that it doesn't actually work.
When remount_optional is present it will always print the error message "mount
-o ro /dev/ufs/cfg /conf/default/etc failed: ignoring due to remount_optional"
even when the mount succeeds. And when the mount fails it still drops into a
shell.
A simple fix to the problem is attached.
