Howdy -
From: Christian Groessler <cpg(a)aladdin.de>
I just last week installed v6 from tape image. I have to admit, I like
working boot images more :-) (Since I only have an emulator and not
An emualtor of course would use an emulated tape image ;) That's
how I typically install. There are instructions and sources to
the program to create the 'virtual tape' from the dump and tar files.
the real thing, I don't have the need to
physically transfer the stuff.)
I keep forgetting that not everyone has a SCSI<->Qbus adaptor :)
(it was _expensive_ at the time but gosh, after 10 years the initial
$ pain is long long gone and I've gotten a lot of use out of it)
Hmm, I just did this now, but I have to admit, I only
browsed the
instructions of most of them. I followed the instructions of 412/413
because I feared I'd forget to update init before rebooting the new kernel.
Yes, screwing up 'init' is, to put it mildly, catastrophic. During
the development and testing of that set of updates I did render my
system unbootable. Thankfully I had a spare OS installed on the
SCSI Zip drive - I just booted from "DU 1" and put back a working
'init' (turns out that a 100MB Zip disk can contain a *full* 2.11BSD
system - not a lot of space left, but it includes all sources and
will boot).
But otherwise I applied all patches to 442, and then
rebuilt the
kernel, rebooted, and did "make build; make installsrc". Seemed to work.
That's fantastic to hear!
I noticed 2 patches, which patched
/usr/src/sys/GENERIC/Makefile, but
this is a generated file I think. At least it wasn't present, because
Yes and No. YES - it is generated by running './config' in /sys/conf.
NO - it's an integral part of the OS as distributed.
I removed /usr/src/sys/GENERIC.
You really didn't want to do that ;)
The Make* files for custom kernels will (100% guaranteed) diverge
from the defaults. That's expected. The GENERIC kernel is a special
case though. When changes are made to the Make* files (overlay sizes
change for example) the patches will not attempt to find and "fix"
any locally created kernels - but the guarantee has always been that
the GENERIC kernel _will_ build, thus the patches presume that the
/sys/GENERIC directory hasn't been removed. Indeed the kernel patches
usually suggest rebuilding GENERIC.
It is a Good Idea (saved my system a couple times) to keep a known
good working _non_networking kernel (i.e. GENERIC) in /genunix. That
way if you are tinkering around (or a bad patch ends up in /unix) you
have something to boot. Many is the time (during development, testing
of course) that I've had to rely on a /genunix to get the system
back alive.
Glad to hear you're current and are not seeing 'df' weirdness. You
may want to upgrade P11 to 2.9 though - that would, I think, have
fixed that problem before you saw it ;)
