Just boot in single user mode so all the filesystems are unmounted or 
mounted readonly.  Then use 'tunefs -j disable /dev/...'.  It will also 
mention the name of the journal file, which can be deleted.

"affect user/system immutable files/dirs".  Probably only included in 
the man page when the port is built with the FLAGS option set.

An additional note: the script that runs my rsync backup also modifies 
the mirrored /etc/fstab to use the appropriate labels for the backup 
filesystems.
