I've just mangled fdisk such that partitioning information can now
be specified via an optional config file. I've been needing a way to
partition a disk from a script (without using expect), and so I mangled
fdisk to do just that. I want to write a perl script for adding SCSI
disks, and a programmatic fdisk was the only piece missing. An example
config file is:
# Set geometry to 1019 cylinders, 39 heads, 63 sectors:
g c1019 h39 s63
# Set partition 0 to FreeBSD, starting at 1 for 2503871 sectors
# (these numbers will get rounded up or down to fall on
# head/cylinder boundaries):
p 0 165 1 2503871
Another example:
# Dedicate entire disk to FreeBSD (this is for a Quantum
# Fireball 1280S):
f 2503872
Would anyone be interested in the changes (including man page updates)?
Should I submit an enhancement request (w/patches), or should I consign
these changes to the mists of time? ;-)
[ One area of concern is that I'm a bit unclear on the start/end address
requirements. Right now, start offsets are being rounded up to an
head boundary, but end addresses are being rounded down to major
cylinder boundaries (every head*sector chunk). Is this right? ]
