No, they're completely not in synch: I'm following the UPDATING recipe, and am getting to the point after installkernel where you have to boot to single-user mode to do the make installworld. That, obviously, has a _6 kernel (and ataraid module) and _5 user-land. The kernel has options COMPAT_FREEBSD5, so that this step works: that's part of the recipe. Is there any particular reason that fsck or mount_ffs from _5 would not work with _6? That would seem to be a prerequisite for the upgrade-in-place procedure. I've done an upgrade-in-place before, on my workstation, and that went without a hitch. The only difference (besides version creep over the intervening six months or so) is that this is on a server server with an ataraid RAID1 mirror array, rather than raw disks. Cheers, -- Andrew
