1. Let's make uuidd optional. Seems it is not widely used: nobody requested openrc script for it yet and some distributions (e.g. rhel) even ships uuidd in a separate package. 2. Add openrc script for uuidd. 3. Systemd units are instaled automagically if systemd is installed. Use systemd.eclass to always install systemd units if USE=uuidd.

For uuidd to actually work with the shipped uuidd service files, uuidd has to be compiled with socket activation support. The man page even states that this is only used in combination with systemd. So maybe add a systemd useflag which compiles uuidd with socket activation support. If you still want to make uuidd optional, there should probably be a use constraint like "systemd? (uuid)". Having a use flag like systemd sounds more logical to me than implementing suggestion number 3 from the bug description.
eroyf: Can you bump this patch with acct-{user,group}/uuidd?
