[Fedora-packaging] User IDs in Core packages?

[Sarantis Paskalis]

Hello,

Is there any recommendation for mandating/enforcing/changing etc. user 
IDs in (previously) Core packages?  There are some rpm packages in the 
upcomming merge that hardcode a specific UID in the specfile to use (I 
was looking at privoxy, which hardcodes the number 73).

The documentation at http://fedoraproject.org/wiki/PackageUserCreation 
recommends fedora-usermgmt but the text seemed to imply that it were for 
Extras packages only.

Is it implied that the default /etc/passwd file should contain the
predefined values for the most important packages and the rest should
find an alternative way?  What is the procedure of allocating UIDs/GIDs 
to those system users (examples are haldaemon, apache, dbus, sshd, rpc 
to name a few).

Should the packages to be reviewed maintain their existing UIDs/GIDs 
hardcoded and document it somewhere?

The default values in /etc/passwd and /etc/group are the following 
(taken from setup-2.6.2-1.fc7.src.rpm in rawhide):

#/etc/passwd
root:*:0:0:root:/root:/bin/bash
