[clue-tech] mount second hard drive

[David L. Willson]

Oh, goldurnit!  That's why I was (and am) ~so~ against Red Hat defaulting to LVM and
SELinux.  As additions to servers, they make great sense, as defaults, not so much.

I don't have the steps memorized for that.  I'll have to rehearse it and come back
later, unless someone else has it.  The output of
# ls -lR /dev/disk
might still be useful.
