Some clarifications and changes:
First, a clarification: we don't get all of the 1GB internal disk from
the SS@0s (we get about half of it, in fact); however, we have things
placed such that we don't actually need all of that space.
After talking with Matt and Jonathan, I came up with a couple of
problems with yesterday's proposal:
First, we need the extra AFS space now, because we need to be able to
do SunOS builds. Therefore, we can't really afford to put a disk on
the news servers until bed is replaced. We'll have to play with
expire times until then.
Second, a correction: it turns out that we will have seven total
external AFS disks, which means we can put a disk on ronald-ann
permanently.
Third, Jonathan felt that we should reinstall the discuss/NFS server
before putting it into production. Under this scheme, rather than
using beacon to replace rosebud, we reinstall old-beacon, migrate
discuss, NFS, gopher, irc, bitnet, etc. to old-beacon, and then
reinstall old-picayune and use it to replace rosebud.
I'm not sure if I agree with that (in particular, do the other
maintainers of services on picayune feel that it would be a better
idea than leaving picayune as the discuss/NFS/foo server?), but at any
rate, it doesn't really change what we do today, which is:
* I bring two disks over at about 3:00, along with some
device-device cables.
* Tonight, we add one disk to ronald-ann and the other to
picayune.
We can move picayune's discuss meetings and NFS lockers to the new
external. This won't really help migration of the RTFM services, but
it will alleviate the disk crunch on picayune, and it will make it
easier to migrate discuss and NFS to another Maxine.
I still don't know where IRC should wind up.
Comments?

At least we don't have to worry about the WWW server.
