Hi Bruno,

The way I see it, we’d define in (guix search-paths) only search paths
that are repeated in several different places, like $SSL_CERT_DIR.

$XML_CATALOG_FILES has 2 users, one of which looks dubious and should
probably be audited, and $SGML_CATALOG_FILES has only 1 user.  Thus, the
status quo seems good to me.

WDYT?

(BTW, the patch would be acceptable for ‘master’ as it does not trigger
any rebuild if I’m not mistaken.)

Thanks,
Ludo’.
