Wow, 14 GB!

The disadvantage, however, is that when compiling stuff on my Sun3/60 u=
NetBSD, the 64-bit off_t's cause lots of troubles. Apart from the file-
system stuff, anything I tried so far compiles fine, but for PGP, for
instance, I had to fix all lseek()'s, and I can't get xsky running yet,
because of similar problems.

Back to kernel-hacking:

I got my new 120M SCSI fully installed now, with the UFS-boot o=
n it.
It's a bit stubborn in that only wants to boot from sd0, so I decided t=

The disks I have are a Quantum 120M, sd0, and a 150M Maxtor, sd2.
on si_options=3D0 or 1 they work perfectly, just like on the 21-aug ker=

With si_options 3, however, I get the same behaviour as with the previo=
test-kernel: generally, things work fine, but when starting X (heavy lo=
ad on
the SCSI?) things start coredumping, and I get stuck in the xdm-login-

reported I couldn't, but that seems to be due to a root partition fille=
d to
the brim (107%) with core-files, the new / is twice as big.)

With si_options 7 the Sun does boot into single-user, and seems just fi=
then. It will hang itself when going multiuser, somewhere in the execut=
of /etc/rc, at varying positions.

Would anyone be interested in some traces, or in general more detailed

How could I make si_options 1 permanent into the kernel?
Are there more kernel-settings to play with?
