I don't think that's correct. The eclass will just use the already
existing UID then (except for the very few acct-user packages that
define ACCT_USER_ENFORCE_ID).

Similar to above, the eclass will dynamically allocate another UID that
is free.

See above.

Also, why would one allocate UIDs in the 500..999 range (1000 is fine,
actually)? Gentoo always had UID_MIN=1000 and SYS_UID_MAX=999.
