Hi,
My question is in brief:
If you run installupdate, do you need to manually add non-standard
options already in your existing kernel afterwards (or use the -i flag
to choose additional kernel options at update time?).
In more detail:
I have recently upgraded some machines using "installupdate", and I have
noticed that some options included in the original configuration file
were not carried forward.
The boxes in question were mainly DPW500au (some AStn 200s) - all going
from 4.0D to 4.0F.
I used installupdate /cdrom and I gathered that the generic kernel is
used but that the environment itself was preserved in that many files
(e.g. /etc/services) would remain intact or be merged using the
original. This has a lot of advantages for me against a fresh
installation as I do not need to restore lots of customised files.
After the installupdate I applied patch kit 3 and after that I made some
additions to the config file to increase shmmax, maxusers and a few
other values that needed to be increased from the default. (though I
could have used sysconfig here).
What I didn't expect was that kernel options that had been added
originally (in the config file after ident = "HOSTNAME") would not be
carried forwards (see below).
It was the lack of XTISO, TIMOD and TIRDWR that drew this to my
attention, but there are a few others also.
Any ideas anyone?
Regards and TIF,
Tony.
