hi
at result of "mount_msdos /dev/fd0 /" i lost the control of the system , and i can't umount fd0 from / or mount /dev/ad0s1a on / (but in similar situation i can do it in linux).
i think it's a good idea to prohibit the posibility of mounting any filesystem in special folders as / , /etc , /dev , /sbin , /etc .... or need a confirmation for mounting in this folder

regards
