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. DES --=20 Dag-Erling Sm=C3=B8rgrav - des@des.no
