I installed gtar and gzip in /usr/local/bin on rosebud (*), and modified
/.cshrc so that /usr/local/bin is in root's path. I dumped the root
partition and /usr/local/afs into /vicepc/{root.tar.gz,usr-local-afs.tar.gz}
with the following commands:
rosebud# gtar cvfplz /vicepc/root.tar.gz /
rosebud# gtar cvfplz /vicepc/usr-local-afs.tar.gz /usr/local/afs
I also copied these (via rcp -x) to ronald-ann:/vicepb, just to be safe
in case we lose rosebud through some unforeseen mishap.
[ Remember that the `z' flag to GNU tar causes it to use `gzip' to
compress/uncompress the file, so that you don't have to use zcat and a
pipe or do it with two commands. For example, to see the table of contents of
the file root.tar.gz, you can just do:
# gtar tfz /vicepc/root.tar.gz
This option is specific to GNU tar, as are --one-file-system (-l for
short) and --exclude (no abbreviation) I didn't use --exclude here, and
/dev/* is included in the root tar file, because I was lazy. Besides,
it's not like you are going to untar it in whole anyway--that would
defeat the purpose of the update!
]
If you want to execute these commands again to get more recent snapshots
of the information, you can. I don't think it's really necessary though
(and it takes a long time.) Most of the stuff won't change between now
and when you do anything, and if there's a disaster, the combination of
these snapshots, the stuff in project.rosebud, and common sense should
suffice.
Good luck with the update.

(*) For those of you who've just tuned in, I rebuilt gtar for AIX 3.1
because the 3.2 binary was exhibiting strange behavior. I threw in gzip
for good measure. These don't need to stay around after rosebud is
updated. They should be removed because after the update 3.1 binaries
will be old. However, I think that in general these utilities are so useful
that they should be installed locally on all servers. I'd say the same
for perl, of course. Actually, we have perl on charon and on the news
servers already . . .
