The uuidd is enabled by default for years (and for RHEL it's strongly required), unfortunately it has no official exception.
Note that uuidd is local-only daemon that uses UNIX socket to listen to libuuid. The uuidd package is very rarely used -- mostly for machines with SAP. It's expected by SAP users that after installation is libuuid able to generate reliable time-based UUIDs without any extra step (like manually enable uuidd).
It would be really nice to have an official FESCO exception.
AFAIK it does not need an explicit exception because it belongs to the general exception: "If a service does not require configuration to be functional and does not listen on a network socket, it may be enabled by default (but is not required to do so)."
UNIX socket is not a network socket.
OK, problem solved (https://bugzilla.redhat.com/show_bug.cgi?id=1094935) :-)
hmmm.. it seems I have already asked for the exception (ticket #949). Sorry.
Anyway, is there a way how to avoid duplicate bug reports from people who scan Fedora package for "systemctl enable" and reports to BZ by scripts? This is not first time someone force me to care about uuidd startup.
