Trying to move /usr

[Ian Smith]

Michael, firstly let me quote the head of your original message, just so
I/we don't get too confused, especially by all the gratuitous re-quoting
of subsequent 'relative irrelevancies' like your dmesg ..

Ok, so /home was its own drive, one slice.  This would suggest that you
didn't have /home as a soft link in / but you should check 'ls -la /' to
be sure that's the case, ie that a link hasn't crept in somehow.  If one
has, delete it.  Also check that your 'old' /usr dir has no link to
/home lying around, which might account for some of this oddness,
especially since your tar and (I'd consider potentially hairy) 'mv * ..'

And you intended to leave /home on the 60G drive?  Its not clear what
you intended to put on the new /user, or was it just an intermediary?

I think I may have called it '/fred' till the process was finished, but
never mind .. back to the more recent, with formatting touched up a tad:

So that /user is your old /usr, right?  Do an 'ls -la /user' and check
its contents are the same as your new /usr below.  Also 'du -d1 /user'
should look like 'du -d1 /usr'.  Neither should contain a link to /home

This looks confused.  I think you want /home (not /usr/home) to be your
60G da1s1d, don't you?  As is, the mountpoint is on the 17G da2s1d,
which would a) actually need to be mounted first, and b) contain a
/usr/home dir to mount it on.

Better would be to mkdir /home, and mount it directly on there.

Right, so you do have a /home directory, not a link there?  Use ls -la
to confirm contents of /, /home and /usr (and /usr/home, if present),
with either the old or the new setup, which might help point out where
this confusion is occuring, especially if there are any links involved.

Also, the realpath command can be useful to discombobulate any links, ie
'cd ~michael ; realpath .'

I'll leave it there, trying to keep the re-quoting level down, but Jerry
and I seem to be on the same page, if reading it in a different order :)
