I've been using 3.00.97 without any issues other than I needed to create
the
file /compat/linux/etc/mtab. I haven't been able to get serial port
mapping
to work, but I've had no issues with ufs drive mapping.
On the other hand this is only a 3_stable box and running XFree86-3.3.X
but
I an running linux_base-6.1.

When things can't get any worse, they simplify themselves by getting a
whole lot worse then complicated. A complete and utter disaster is the
simplest thing in the world; it's preventing one that's complex.
