That's how I found out about the bug in the namei() kernel function
(NULL pointer dereference). I also tried to run VP/ix in kernel POSIX
mode, and the system paniced. I posted a binary patch to fix this
problem. With this patch installed, you will find that VP/ix no
longer causes a kernel panic, but it still won't work. If I remember
correctly, this is because VP/ix tries to open the serial ports with
the O_EXCL flag, which, in POSIX mode, obviously isn't allowed for
devices.

BTW, ISC told me that they already knew about the bug in namei(),
and that it is fixed in their current (internal) release. However,
they didn't tell me whether they intend to release a fix disk for
this problem, or whether we have to wait until the next major
release.
