This indicates that init was killed with a SIGHUP (probably
as part of the upgrade process). Then, when the libc changed
underneath init, the kernel couldn't restart it and panicked.

All Unixes, I think, will panic if init dies unexpectedly.
And, when that happens the NetBSD kernel will drop you into
the debugger. Test this yoirself by booting into single-user
mode, then, at the prompt:

# kill -ABRT 1

Run an fsck and mtree against the specs. Your upgrade
probably went OK, if no serious errors are reported
by either.
