Have not done that yet. My current best plan (which I'm not really
crazy about, but haven't come up with anything better) is to do
121 "find /home -uid ... -exec chown {} +" and 37
"find /home -gid ... -exec chgrp {} +" commands. This is also called
"Let's modify every inode in the filesystem. Twice." Oh, well, the
ctimes are blown up by the migration anyway (as they really should be).
I have to be careful, if there are any IDs that are used on both
systems, but with different associations, to do the change in
the right order (sigh). I could try to get really fancy and just
find the distinct combinations of "uid:gid" and do only one
"chown uid:gid" for each file, but, getting it done will be more
important than being pretty at some point.
Open to suggestions!
(I'd generate the commands via a script, of course.)
And, of course, there's the whole matter of migrating the passwords...

It probably is, but I see so much of other servers running on
similar hardware with a certain other operating system that
have a reguluar 30-day scheduled reboot, it still delights me.
I just wanted to share my delight!

No - though this system does "real work" - it is actually located
in my home. It probably isn't unusual for data center machines,
except those that are on some sort of regular "uptick upgrade"
schedule.

So it would seem!
