The question is not whether the UIDs have or are changing .. its whether they were the same in the first place. With the exception possibly of two+ identical installs (ie. same base image, same portage snapshot, same install sequence, same USE flags, etc etc etc) the case of a non-identical setup may cause slight differences (a common "off-by-one" error) in UID allocation if "next available" is the default allocation option.On Sat, Jan 28, 2017 at 8:54 PM, Michael Orlitzky <mjo@gentoo.org> wrote:

I forgot to mention a few of the advantages of having really-fixed UIDs.
First, it makes the code simpler. Yup, cool.
It also lets us play a nice trick and use the UID as a subslot, so that
if some sys-user/foo package ever changes its UID, everything depending
on it can be rebuilt to use the new UID.
That's nonsense for reasons already mentioned by rich0. UIDs don't change except in the case of an admin doing it manually.
