Hi, Doug!
Many thanks for the info!
Just FYI, I'll tell you how I have got the work done:
1) Of, course, with `fdisk(8)', I modified the slice table, getting rid of
the Linux one and creating a new -identical- slice for FreeBSD. BTW, I put it
in slot #3, instead of #1. So it now reads:
The data for partition 3 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 1620864, size 491904 (240 Meg), flag 0
beg: cyl 402/ sector 1/ head 0;
end: cyl 523/ sector 63/ head 63
2) After rebooting, the hard task: creating a new disklabel.
Using `disklabel -e' on a new slice is of no use, since this option expects
that any label exists. After browsing the man page many times and many other
failed tries, I concluded that my best bet was with `disklabel -R -r disk
protofile'. So I took a copy from the wd0s3 label -the original BSD slice-,
and modified it to fit the parameters of the new slice. So:
# disklabel.s4 : protofile for /dev/rwd0s4c:
type: ESDI
disk: wd0s4
label:
flags:
bytes/sector: 512
sectors/track: 63
tracks/cylinder: 64
sectors/cylinder: 4032
cylinders: 122
sectors/unit: 491904
rpm: 3600
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0 # milliseconds
track-to-track seek: 0 # milliseconds
drivedata: 0
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
c: 491904 0 unused 0 0 # (Cyl. 0 - 122)
f: 491904 0 4.2BSD 0 0 0 # (Cyl. 0 - 122*)
BTW I had to MAKEDEV the wd0s4? special files. And then:
disklabel -R -r /dev/rwd0s4c disklabel.s4
3) New reboot and all went fine: newfs the new rwd0s4f partition, mount, etc.
>> Er, BTW, FreeBSD version is 2.2-960326SNAP.

Yep. I'm gonna order the most recent SNAP version ASAP!
So, thanks a lot, Doug!
