I was given the advice to use ext2 file systems so that I could mount the Linux disks from FreeBSD but it seems that we have support up through ext4? Or perhaps the port of efs2progs is necessary for that? I don't mind using ext2 if that's the best choice, but if I can use the newer (better?) option that's fine too. What I am looking for is the "safe" choice, a way to mount the partitions that a) won't crash FreeBSD, and b) won't cause data loss. This would be for both FreeBSD 7-stable and 9-current. On the other side, I'm reading up on mounting ufs2 from Linux, and it seems r/w support is still considered "dangerous." I can mount r/o just fine, but I'm wondering if anyone has actual experience with using r/w on a regular basis. In addition to just wanting to be able to access stuff that is on one OS' disk from the other on an occasional basis my grand scheme is to have all/part of a home directory that is shared between OS'; so that's my definition of "safe." So far it seems that the best/safest alternative is an ext2 partition, which is Ok, but I'd prefer to stick with ufs2 if possible since FreeBSD is still going to be my main platform.
