/opt is a location filled with vendor detritus on a lot of systems -
sometimes managed by rpms, sometimes not. It's not uncommon to have /opt
automounted via nfs. Additionally, on some workstastion systems /opt is
a separate drive managed by the 'local admin' of the machine and filled
with whatever 3rd party software they need for their instance.

/usr is frequently given different mount options (like noatime, for
example) or mounted readonly to prevent unnecessary writes to the
system.

Additionally, since our software in fedora has a trickle down impact on
users in rhel-land I think you'll find that this will have to be done,
eventually for them.

Finally, I'm more than a little concerned by the tone of comments in
that bug report. It's troubling.
