New description:

 fhs-2.3 says:
 {{{
 /usr is the second major section of the filesystem. /usr is shareable,
 read-only data. That means that /usr should be shareable between various
 FHS-compliant hosts and must not be written to. Any information that is
 host-specific or varies with time is stored elsewhere.
 }}}
 `package.conf.d` is not shareable, as different machines may have
 different packages installed, so we should put it under /var instead.
