Hmm, didn't we discuss this already? All we need to do is change the
defaults in fdisk so it rounds partition offsets and sizes to a multiple
of 8 sectors (or 16 for future-proofing) instead of aligning them with
fictitious cylinder boundaries. Bsdlabel, as disklabel is properly
known, already DTRT: by default, the first partition starts at offset
16. Just make sure you specify sizes that are divisible by 8 or 16
blocks (not an issue if you use the M or G suffixes). Sysinstall
operates in megabytes.
