partitions story #1 (was: Re: Re: Disk partition names)

Harlan posits one disk-partitioning story:

[I assume "slice" == "partition"]

Can we chomp into just this one (to start)?  I'm interested
in concrete example(s) of names before and after, and what
Arusha stuff you (wished you could have) used to make the
change.  Here's what I might do...

* Before: the machine has usual /, /usr, /var, /tmp, etc.,
  partitions; plus /._disk1 partition (which is simply the
  rest of the boot disk), plus /._disk2 partition (which
  spans a whole second physical disk).

  NFS-available stuff from this machine lives in
  /._disk<N>/<map>/<thing>; for example, my home directory
  might be {on, exported from} /._disk2/home/partain.

* I'd just put a big partition on the new physical disk, and
  call it /._disk3; no Arusha help.

* I move my home dir to /._disk3/home/partain/.  I do these
  by hand, but Arusha stuff could do...

  * look around to make sure no hosts have the old location
    mounted
  * adjust the /home automount map site-side
  * ditto /etc/exports and/or backups disklist (as required)
  * what else?

[The sidai "disk chunks" (dchunks) stuff does a *little* of
the latter.]

Is this any use?  (I like "running X turns Y into Z"; fits
my simple brain...)
