However, edmundo@rano.demon.co.uk writes:
"In addition to having a Sun partition table, to be able to
boot from the disc, the first partition, /dev/sdX1, must
start at cylinder 0. This means that /dev/sdX1 contains
the partition table and the boot block, as these are the
first two sectors of the disc. Therefore you must be
careful what you use /dev/sdX1 for. In particular, you must
not use a partition starting at cylinder 0 for Linux swap,
as that would overwrite the partition table and the boot
block. You may, however, use such a partition for a UFS
or EXT2 file system, as these file systems leave the first
1024 bytes undisturbed. */

starting at block 0 in an md, or the label will
