Safely mount OS X UFS filesystem?

[Thor Lancelot Simon]

Can I, on a system running FreeBSD 6.2 or -current, safely mount a
UFS filesystem created (and used) on Mac OS 10.4.10?  These filesystems
are UFS1 (at fslevel 3) with big-endian datastructures in the metadata,
4k blocks and 1k fragments, and a few minor oddities in their layout;
they are pretty much exactly the UFS NeXT used on their workstations.

If so, Will such a filesystem be safe to mount under OS X after I use it
on FreeBSD?

I seem to be able to mount these under NetBSD though the snapshot code
complains that inodes 64 and 16384 are not dedicated to snapshots.
