I have finally eliminated the need to keep NT on this machine and I
would like to repartition the disk to give the rest of the space to FreeBSD.
This leads to a few questions:
1) If I use Partition Magic to move the FreeBSD partition
and its contents, will FreeBSD boot ok. Or does it keep
track of the partition info in a special FreeBSD specific
place. For example:
% df
Filesystem 1K-blocks Used Avail Capacity Mounted on
/dev/wd0s3a 127151 31285 85694 27% /
/dev/wd0s3f 3621655 2410600 921323 72% /usr
/dev/wd0s3e 127151 14571 102408 12% /var
Will FreeBSD know that wd0s3a starts at the beginning of
partition 3 or will it "know" that wd0s3a starts at
cyl 254/sector 1/head 0?
2) If FreeBSD uses its own "records" about the location of
everything, what can I do to "fix" it after I move the data?
3) Assuming all else goes ok, is there a "growfs" tool to enlarge
/usr? Or must I dump/newfs/restore?
I am running 2.2.6, by the way. I will upgrade to 2.2.7 if that buys me
anything. I will also do a level 0 dump of everything, just in case.
A couple other bits of info:
% disklabel wd0
# /dev/rwd0c:
type: ESDI
disk: wd0s3
label:
flags:
bytes/sector: 512
sectors/track: 63

8 partitions:

% fdisk
******* Working on device /dev/rwd0 *******
parameters extracted from in-core disklabel are:
cylinders=784 heads=255 sectors/track=63 (16065 blks/cyl)
parameters to be used for BIOS calculations are:
cylinders=784 heads=255 sectors/track=63 (16065 blks/cyl)
Media sector size is 512
Warning: BIOS sector numbering starts with sector 1
Information from DOS bootblock is:
The data for partition 1 is:
sysid 7,(OS/2 HPFS, QNX or Advanced UNIX)
start 63, size 3068352 (1498 Meg), flag 0
beg: cyl 0/ sector 1/ head 1;
end: cyl 190/ sector 63/ head 254
The data for partition 2 is:
sysid 6,(Primary 'big' DOS (> 32MB))
start 3068415, size 1012095 (494 Meg), flag 0
beg: cyl 191/ sector 1/ head 0;
end: cyl 253/ sector 63/ head 254
The data for partition 3 is:
sysid 165,(FreeBSD/NetBSD/386BSD)
start 4080510, size 8514450 (4157 Meg), flag 80
beg: cyl 254/ sector 1/ head 0;
end: cyl 783/ sector 63/ head 254
The data for partition 4 is:
