Not a "solution", per se, but I've been able to run servers
a long time with symlinks from /var/foo to /usr/var/foo,
and so on.  /var/log is a particularly good candate IMO,
but I see no reason that you couldn't try it with most
any subfolder(s).

The problem there is that it'd be best to do the symlinking
when the box was in single-user, and I doubt you have console
access in the situation you describe.  In should be possible,
depending on the box's application, to kill the daemon(s) using
said folder, mv the data to /usr, create the symlink and restart
the daemon(s), but it's maybe a little touchy, as I said, depending
on what you're moving and how many customers it would affect,
