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.
