Right. I'll bear that in mind, might even look into it when I get my fast
connection bac after christmas.

That's what I've done with linux installs in the past, I'm just not
familiar enough with netbsd yet :&/

We have a problem:
UVM: pid 16 (mount_nfs), uid 0 killed: out of swap
I recon the 2M ramdisk, which is full, is a bit too much for my poor 4M
vax :&(
Now if I could get the root mounted over NFS and not use a ramdisk, I
think we could be in with a chance. I suspect that would be wanting a new
kernel tho, which I don't think I can make here very easily.
Bye for now,
Matt
