Hello again from Gregg C Levine
Yes, Ian. That's exactly what I mean. Of course I was thinking of RL02
images, rather then a RK05 image. Which one did you choose? And can
you post something explaining the steps?
And your response was the simpler form, which is what I wanted.
David's comment was a bit obtuse, but I got it. By the way? Are you a
WB fan? As in Warner Bros. Animation. I'm partial to the wisdom of B.
Bunny.

I don't remember the details in my head and I'm also typing this on the go, but
in 4.3BSD fsck does work on the block device and then you reboot with, well,
reboot, and it works.

Carl Lowenstein:
Isn't this really true of Unix systems of any age, when doing fsck
on a mounted root file system?
Some middle-elderly BSD systems--4.1 and possibly 4.0--
managed the buffer pool in such a way that the super-block
of a mounted file system was kept in the original buffer,
with device and block number correctly stored in the struct
buf header. Hence if fsck wrote to the block device rather
than the raw one, the super-block came out right even when
checking a mounted file system; in particular there was no
need to reboot.
This convenience was abolished in either 4.2 or 4.3 (I am
travelling right now and cannot check manuals and
sources). I never quite understood why, though I never
looked at the source code in the later systems. The
scheme found in most current systems, in which the
root starts out read-only, is a better idea anyway.

Hello again from Gregg C Levine
Just for the sake of an argument, has anyone actually managed to
restore a volume from the collection on the ftp server, back to an
originally sized disk pack? Or for that matter restored a system so
that it behaves as advertised under E-11?
No, folks that machine I "have on order", has not arrived. Once again
I am searching for information for a future project. One that might be
happening sometime this week, or even later this month.

Yes, it does. A bug in the parsing. Why it does not affect all
the lines is unknown. Perhaps some trailing whitespace caused the
parser to exhibit the bug.

What is the exact message? I did a "strings /unix" and could not
not find a string that looked mentioned unknown or interrupt.
That would seem to indicate that the device is interrupting but not
at the expected vector.
It is possible to use 'adb' to look at the contents of the vectors.
adb -k /unix /dev/kmem
0344/o
will show the contents of the 0344 vector. The value there should
be equal to 'cnrint' (or cnxint - I forget which comes first).

Definitely worth trying.

Ah, ok. Thanks for the correction. I misread the initial mail item.

:)
I did the the same thing - wondered why I could never get a clean
file system. Then I realized what was going on.

Not really. Newer systems mount the root filesystem read-only
while running fsck. After the filesystem is verified as clean
then it is upgraded to read-write.
Older systems such as 2BSD can't run with a read-only root
filesystem that I know of. At least not easily/happily. Might be
possible (the ability to upgrade a ro mount to rw is present) but
it's never been a priority to look into it ;)

Isn't this really true of Unix systems of any age, when doing fsck
on a mounted root file system?

Anyone thought of asking him if he could contribute his Concurrent Pascal and
Solo, etc, to PUPS?
Just a thought.
