Ok, here's the scenario:

I want to have my default swap partition on another drive than the one
occupied by root. So, I change SWAPDEV in /usr/sysgen/system
accordingly and I remake /dev/swap and /dev/rswap. I then rebuild the
kernel. Everything seems fine, the values have been changed in the
kernel. So I reboot and guess what, it still uses the old default swap
partition (I want xyl0d1s1 and get xyl0d0s1). Anybody have an idea
what is wrong here? By the way, this was done on a 4D/240S. I tested
the same procedure with a 4D/20 (a different partition on the same
disk) and it worked...

Also, since we want to move our swap space and use the whole disk, we
figured that it would be a good idea to have a miniroot that starts
from a partition of our choice. So I naively defined the constant
MINIROOT in /usr/sysgen/system (CCOPTS). Obviously, that's not all
there is to it because when I tried this kernel, the machine
complained about not finding devnm (yes, I know what devnm is). I even
tried to poke the values I wanted in the miniroot unix.IP6 file and
got the same error.

I'm aware of the fact that we can add swap space. But that's not what
we want. We want to move it.

Any idea, anyone (SGI maybe)?


(Note: I mailed something about this directly to info-iris but for
some reason it was not re-submitted to usenet. So here it is.)
