NAME
     mksnap_ffs	-- take	a file system snapshot

SYNOPSIS
     mksnap_ffs	snapshot_name

DESCRIPTION

     file remains "root".  The mode of the snapshot is set to be readable by
     the owner or members of the "operator" group.

EXAMPLES
     Create a snapshot of /usr/home file system	and mount the snapshot else-
     where:

	   mksnap_ffs /usr/home/snapshot
	   mdconfig -a -t vnode	-o readonly -f /usr/home/snapshot
	   mount -o ro /dev/md0	/mnt/

SEE ALSO
     chmod(2), chown(8), mdconfig(8), mount(8)

     tem panic when no free blocks are found.
