Only to a partition (hey, this is real VM ok???? none of this swapfile
shit like windoze :) When I had OS/2 2.0 running, I didn't like the
idea of a swapfile there either (I gave the swapfile it's own
partition :)

Apparantly the default BSD (not 386BSD, BSD) Net/2 dist of csh has
problems with pathnames with a multiple of 4 chars in them... I don't
experience the prob, since I use tcsh - which I recommend you to get.
The patch for csh was posted here a few days ago...
It's tacked on the end of this post...

It's normal... Whenever root logs in, this is classified as a certain
level of 'notification' for the kernel ('auth' I think). The initial
way that 386bsd is configured is to output to /dev/console some of the
log messages. Here is the /etc/syslog.conf file which defines this:
--
*.err;kern.debug;auth.notice;mail.crit /dev/console
*.notice;kern.debug;lpr,auth.info;mail.crit /var/log/messages
mail.info /var/log/maillog
lpr.info /var/log/lpd-errs
*.err root
*.notice;auth.debug root
*.alert root
*.emerg *
--
As you can see, any mesg of type auth.notice gets dumped to the
console. 2 solns:
1. remove auth.notice from the 1st line
2. change /dev/console to /var/log/console, and
put the messages in a file :)
Read the manual for syslog and syslogd for more info.

Dunno...

Well, for SCSI HD's I'd recommend:
Conner 360 (CP3360) or 540 (CP3500). Fasted drives we tested for that
size. The Quantum 240 is pretty good too. (I have a lot of benchtest
data at work that some guy did - on Mac's - but data used a lot of
different benchtest techniques... I personally like the 540 - we run
A/UX 3.0 on it at work :)

CSH FIX FOLLOWS...

I have run into the csh segmentation violation bug, and I was too lazy to
install the simple "alloc + 4" bugfix, so I tracked it down. It seems to come
about whenever you are in a directory in your account which has a pathname
length which is divisable by 4, for instance, /users/kml/g. To test,
create such a directory, enter it, and sorta execute alot of commands.
Sooner or later, csh will die.
The fix is to add one to the space allocated for a string in the
dcanon() routine where it normalizes directory names which include
the string defined for the environment variable 'HOME'.
Have fun,
Kevin

you get the idea about the change...]
