In my machine, FreeBSD 5.0-current, NetBSD 1.6-BETA and OpenBSD 3.1 are installed, and they share some partitions, e. g. /home, and had no problem. Now, however, after FreeBSD mount those partitions once, when NetBSD and OpenBSD mount those partitions at boot time, fsck stops with error number 8 and *BSDs fall in single-user mode. `fsck -y' doesn't succeed too. If I run `fsck_ffs -b 32' on NetBSD and OpenBSD, fsck finishes completely. But FreeBSD mounts those partition once, NetBSD and OpenBSD fall in single-user mode again. Though this phenomenon doesn't happen with kernel at 21 June 2002 6:15 UTC, that happens with one at 6:20 UTC. Differences between them may be UFS2 codes. So UFS2 may prevent some *BSDs from mounting shared partitions.
This phenomenon is, however, not so critical, because NetBSD and OpenBSD can mount those partitions without fsck checking. If I run `mount -a' and `exit' after NetBSD and OpenBSD fall in single-user mode, those *BSDs start with no problem. No file is lost. Can you let your *BSDs share some partitions? If anyone can't do it, I'll write send-pr. Below are messages of FreeBSD dmesg and mount: Copyright (c) 1992-2002 The FreeBSD Project.
