Hello Tim
I did what in the handbook under article 26.6.5.2. is described but not shure
how I can write a new boot block to the disk. Here is what I think is correct:
Output from df and bsdlabel mfid0s1:
# df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/mfid0s1a 989M 378M 532M 42% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/mfid0s1d 989M 16K 910M 0% /tmp
/dev/mfid0s1f 388G 2.6G 354G 1% /usr
/dev/mfid0s1e 182G 43M 167G 0% /var
# /dev/mfid0s1:

# size offset fstype [fsize bsize bps/cpg]

b: 8388608 2097152 swap
c: 1246081662 0 unused 0 0 # "raw" part, don't
edit
d: 2097152 10485760 4.2BSD 2048 16384 28528
e: 394264576 12582912 4.2BSD 2048 16384 28528
f: 839234174 406847488 4.2BSD 2048 16384 28528
My opinion is:
bsdlabel -B mfid0s1
Is that correct?
