- Check superblock magic. Overwriting the first sectors of partitions using other filesystems than BFS is likely to cause trouble. - Check presence of bootcode in the same version, as well as the correct partition offset. - Tell the user when the partition was already bootable and nothing was done, hopefully this will finally stop people from thinking that makebootable is of any use (it isn't, Installer already does the work).
