Well, we were talking about split administration where one local admin
is not aware of the user the master admin manages.

And then the same master admin injects amada under
/usr/local/{bin,lib,...} and the local install (of a different
version) calls half under /usr and half under /usr/local (and remember
/usr/local takes precedence).

This scenario is just as plausible as the one with an amanda user (I'd
argue that a master admin centrally installing a backup solution is
far more common than having Amanda Lear with her first name in any
account), still we will not make loops and hardwire /usr everywhere,
the sources, specfiles etc.

That's a different story, we can't chose that number, that's given by
the FHS.

You mean to choose at installtion time that httpd is not using the
user apache but say Donald? What about all the other packages that
make their bits owned by apache then? How would these packages know
what the base package is using for users and groups?
