Without looking through the ebuilds, I'd guess the ebuild runs
useradd -r
which will always lead to your problem sooner or later.
IMNSHO, /etc/{passwd,shadow,group} really should be part of the base install
with all daemon users pre-defined. Use the range 1-99 for this, it will take a
very long time to accumulate more than 99 daemon UIDs and one can confidently
know what UID a given system user required by an ebuild ought to be.
The implementation is obviously more complex than dropping a file on the file
system, so a simple API is required. Nonetheless, the idea is still sound.
The alternate is to expect users to know to run
find / -nouser -o -nogroup
at the magic points where it will be useful. Which is ludicrous.
