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