I was just looking at the bsdlable manpage, and it says:
"For partition `c', * will be interpreted as an offset of 0. The first
partition should start at offset 16, because the first 16 sectors are
reserved for metadata."
I normally use sysintall for new slices, but a few days ago I edited an
old slice to turn the old root, swap, /tmp and /var partitions into a
single partition d for a squid cache, and I ended-up with this:
$ bsdlabel /dev/ad0s2
# /dev/ad0s2:
8 partitions:
# size offset fstype [fsize bsize bps/cpg]
c: 141853950 0 unused 0 0 # ...
d: 5242880 0 4.2BSD 2048 16384 28552
f: 16777216 5242880 4.2BSD 0 0 0
g: 119833854 22020096 4.2BSD 0 0 0
I'm wondering if I should put in an offset of 16 for the d partition
