Abject apologies for being such a dunce, but I need help.  This is what
I've done so far:

Compiled/rebooted a new kernel with "INVARIANTS" + "INVARIANT_SUPPORT"+
"makeoptions DEBUG=-g" + "DDB".

nfs-mounted(ro) the root directory of the linux box on /mnt.

cd /mnt/usr/local/lib/mozilla-1.8a5/
ldd ./mozilla-bin (this also produces a missing-lib error on FBSD)

Now I have the 'blocked on lib' error and an uninterruptible wait
on the 'mozilla-bin' process.  So far, so good.

Now I hit 'ctl-alt-esc' and all I get is a skull-and-crossbones icon!

Okay, I switch to a pseudo-terminal and login as root and try the
'ctl-alt-esc' again -- absolutely nothing happens.  Nothing!  :o(

I was expecting to start ddb so I could get a coredump.  Can you
tell me where I went wrong (in baby steps, of course)?

The linux box is one-giant-partition-for-everything, and I mount
its root partition on /mnt.
