In particular, the Linux second stage boot code will not work for FreeBSD, which expects the second stage boot code to pass it much information from BIOS space that is unavailable in protected mode. In addition, using the FreeBSD second stage boot will not by default recognize the unsliced partitions Linux uses as mountable as root, nor will the kernel recognize ext2fs by default (variant root FS types is one argument pro a bootfs). At a minimum, your root FS will need to be UFS at present, unless you plan to use unredistributable local hacks to put the GPL'ed code statically in a BSD kernel. > > does freeBSD support the ext2 file system from linux w/o > > reformatting? > > No, sorry. You'll have to convert everything to ufs. Yes, but not for root (see above).
