I saw a similar problem on my SE/30 when I updated to 1.2. I had booted
single user and then installed all the tar files. When I rebooted, I got
the "signal 10" messages. I then rebooted single user and did an fsck. One
file was sick, and when I fixed it, all was well. IIRC, the sick file was
init, which probably stemmed from the fact it was in use while I was
installing. When it got unlinked, it stayed around (as it was open). Since
there was no way to unmount the root fs with init closed, there was a
problem. :-)

I think the moreal of the story is to move init to something else and
install the new init, rather than installing via a tar x... --unlink.

Take care,
