...wWhich would include running the script in %post.  We give /srv and /opt
to the sysadmin exclusively.

For the things packaged in Fedora, the correct thing to do would be to patch
everything to look in %{_bindir}/ for the programs (perhaps in addition to
/opt/aws).  If parts of the stack of dependent software is not ever going to
be in fedora, those pieces should be changed in the outside packaging.

Providing a script to create the symlinks that the sysadmin can optionally
run after the rpm is installed is okay as a temporary compatibility measure
although I would still urge/submit patches to upstream to search %{_bindir}
for the required programs.
