[aur-general] Assigning Numbers to User and Group

[Steve Holmes]

I've been working on an alternate PKGBUILD for speech dispatcher where
it would run as a system wide service by default.  In doing this, I
created a user, speechd and a group, a11y so I could keep the speech
environment secure through the unix domain socket.  So far, it seems
to be looking and working pretty good.

Anyway, I don't know how numeric IDs are assigned to users and groups
- especially those intended to be used by system daemons like mysql or
postgreql.  I have postgresql on my box and it does this same kind of
thing with user and group creation.  Do you know what values I should
be using so I don't conflict with other potential packages?

If you want an example of what I'm talking about, see the PKGBUILD
script for postgreql it creates a user and group on the fly as needed.
I plan to do the same with my project.
 
Thanks for any help you can.
