Well, after getting a new disk for my notebook -- it's actually second-hand, and it does already contain a working Linux installation. I've decided to keep the Linux by now, and rather install FreeBSD into that part of the disk that used to be /usr2 under Linux. Ok, fine, with the advent of the slice code, i should even be able to share Linux' swap slice. A few quirks with the installation procedure however: o Sharing a foreign slice and assigning it as swap seems to be impossible, even in wizard mode. o Using the existing swap slice by using two FreeBSD slices failed, since the original layout was: wd0s1: Linux root wd0s2: Linux swap ==> first FreeBSD slice (wd0s2b for swap) wd0s3: second FreeBSD slice (wd0s3a as /) The installation program didn't complain, but it failed to create the root file system since it's using the ``compat slice'' wd0a to create the root (hence it tried to newfs /dev/rwd0s2a). o I decided to shuffle the slices around in wizard mode (with the idea in mind to move Linux' idea of the swap from hda2 to hda4 finally), so the intented FreeBSD root comes first in the fdisk table. Bummer: since i wanted to keep the existing swap at the same location (well, for no good reason :), i've first created wd0s2 in wizard mode, but used the region of the disk physically located at the end, and i've finally assigned the remaining (intervening) sectors as wd0s3 (so it wouldn't become the compat slice). *Now* sysinstall complained that i could not use this region for a root file system. Strange. This decision has not been made based on the fdisk slot #, but on the physical location on the disk. (I've finally convinced it by deleting that slice, assigning /, and re-establishing the swap region.) My wishes: o it should be possible (at least in wizard mode) to assign an arbitrary region of the disk for swapping; in particular, the Linux swap is identifiable (ID 0x81) and could be offered as a valid swap slice in the first place :) o the decision whether a file system is acceptable as a root fs should be made based on the fdisk slot #, and not on the physical location on the disk -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
