This is a 4.0-STABLE system:
$ cd /dev && ls -la da[01]s1?

This is a different 3.2-RELEASE system:
$ cd /dev && ls -la da[01]s1?
brw-r----- 1 root operator 4, 0x00020009 Jul 7 1999 da1s1b
brw-r----- 1 root operator 4, 0x0002000c Jul 28 1999 da1s1e
brw-r----- 1 root operator 4, 0x0002000d Jul 29 1999 da1s1f
It seems to me like I've got the correct character devices
created under 4.0-STABLE, and yet there still isn't a valid
filesystem that fsck can find on /dev/da0s1a, which I know to be
false because I can reboot the machine and bring it up in 3.4-STABLE
on that disk.
So, I'll repeat the question -- what do I have to do in order to
get 3.4-STABLE disks readable under 4.0-STABLE, and/or 4.0-STABLE
disks readable under 3.4-STABLE?
