[gentoo-dev] Gentoo standard UIDs

[José González Gómez]

Hi there,

I've recently written an ebuild for a package that needs to create an user,
and I have several questions regarding this issue.

Is there anywhere I can find the list of standard UIDs/GIDs used in Gentoo?
Is there any kind of linux/unix standard regarding this? I've been googling
for this, but although there seems to be some type of convention regarding
reservation of UIDs in some range (0-100, 0-500, 0-999 in useradd man page),
there doesn't seem to be anything resembling a standard. I've also noticed
that each distribution seems to use their own list of reserved UIDs/GIDs.

I also took a look at
http://devmanual.gentoo.org/ebuild-writing/users-and-groups/index.html, and
there they say that you shouldn't hard code the UID/GID, so does enewuser
use some kind of algorithm to keep the new UID/GIDs in a given range? Can I
be sure that a UID generated by enewuser won't collide with some range I
reserve for non system users?

Thanks in advance, best regards
Jose
