There are three known issues:

- "mount -u -o log" doesn't work yet, so you can't have logging enabled on the root filesystem. "mount -u -o log" is disabled in this patch
   (see around line 222 of sys/kern/vfs_syscalls.c).

Related to this is also a problem when the device node for a
logged filesystem isn't on a ffs filesystem (for example if
you have a tmpfs /dev).  PR kern/38057 has more details.  For
now, you need to use an ffs /dev to use journalling.

Any idea if APPLE_UFS would do? We treat is as ffs from outer space after all. ( I mean holding the device nodes - I don't think I can reasonably expect journalling to work on APPLE_UFS filesystems at all )

have fun
