I think the useful place to put it is to get aerospike to publish
their SRPM, especially their spec files. I'm looking at the RHEL rpm
for their c-client tool, and it shoves some things in /op, and some in
/usr/lib for the 64-bit version, which rather violates the /usr/lib64
location for the libraries.

I looked at this once before and it started making me twitch. Anyone
who publishes a system specific tarball, and puts the sources and
several RPM's *inside* the same tarbal but can't be bothered to
include a .spec or SRPM is just being goofy.

The "FileSystem Hierarchy", "File Hierarchy System", and its other
three-letter descriptions had their last official release in 2004.
It's in the process of an update to version 3.0. The beta version is
at http://www.linuxbase.org/betaspecs/fhs/fhs.html. It's pretty clear
that "/opt is reserved for the installation of add-on application
software packages.".

It's common for third party packages that require their own
non-system-standard libraries and binaries for Perl, Python, MySQL,
HTTPD, and god knows Python and Ruby use /opt to have a modular
installation that does not step on your system libraries. God knows
that commercial software vendors use it, and even some open source
vendors like Opscode use it for "chef" software.

Also note that Fedora does not follow the FHS word-for-word. The
merging of /bin with /usr/bin, /sbin with /usr/sbin, etc. is a clear
violation of even the latest proposed FHS. And the use of
"/var/run/meda" for user-owned mounted media, built into "systemd", is
a pretty clear violation of the specification for  all three "/var",
"/run", and "/media. Getting violated 3 ways at once, well, I hope it
was thrilling for *everyone*.
