Eh? What do you mean with "floating"? That you refuse to keep the base
value constant? Well, there are lots of other ways how to damage
installations.

And with useradd -r, how do you get the same uid/gid for a package on all
installations, when you want that?

In the same way you can install the wrong distribution on machine number
23 e.g. because you insert the wrong media. ;) fedora-usermgmt setup can
be made available at installation time.

Has nothing to do with this thread.

As long as you continue with your very own definition of "fixed", it's
hopeless anyway.

You can't think of any environment, where predictable uids/gids make
sense?

Because default behaviour is transparent and just like "useradd foo".

According to your murky theory, we should worry a lot, because none of the
packagers and reviewers, who have dealt with fedora-usermgmt, have
questioned the default behaviour.

fedora-usermgmt is not about fixing something, but about adding a
feature. Well, that's my point of view. I'm not a hardcore advocate of
using it everywhere. But I don't understand why a simple EPEL steering
decision is wrapped into a crusade against an optional tool.
