Dear Philip Moyer,
If I fully understand the whole matter, you have to remake your *disk*=20
and *slice* entries at this stage (stage 15) because you need to=20
access them in the subsequent reboot (s.u.m.). So, strictly speaking,=20
you should remake only those disks and slices which are necessary for=20
the uprading procedure (e.g. because they will contain the upgraded=20
pieces of your system :-)
Personally, I followed Nik's make world tutorial as usual (steps >20):=20
ie I ran mergemaster and then I remade *all* the devices ("/dev/sh=20
MAKEDEV all"). =20
If you do so, you will automatically (re)make a good number of them=20
(ie a "standard set", so to speak.) But you *MUST* make slice entries=20
(e.g. ad0s1a) and all those entries outside the "standard set".
You might want to check what is remade (e.g. as indicated in the=20
hanbook), and, mutatis mutandis (ie check the new names for the device=20
nodes), make what is missing. AFAIK, in 4.0-something (current,=20
release, or "stable"), the concept of block devices has disappeared=20
although, in the early stages, "compatibility" devices nodes will=20
still be present (e.g. wd*).
Also, you might want to *write down* what you do as well as recording=20
your session (script command): if something goes wrong, somebody will=20
be able to help you.
BTW, after upgrading to 4-(then)CURRENT, I remade the world once again=20
to make sure that *all* the components were ok: the logs (and the=20
script command) are your friends :-)=20
Good luck,
Salvo
