After skimming the Debian Emacs Policy, I think there might be one
useful feature to copy: All emacsen have a /etc/emacs/site-start.d
directory in common, which is used in case there is no
/etc/<flavor>/site-start.d directory:

|   directory will take precedence over those in the emacs common
|   directory.
`----

This might be useful to support multiple versions of Guile on a
system, but nevertheless allowing packages that do not depend on a
specific Guile version to place their scripts into /etc/guile/init.d.
