Bug#1067845: adduser: Reserving uid/gid from the uid/gid pools

Package: adduser
Version: 3.134
Severity: wishlist
Tags: patch

Dear Maintainer,

The UID_POOL (and GID_POOL) files contains UIDs that should be used for given
name. It would be helpful to reserve the UIDs for the future, so that the order
of adding users to the system won't affect the usability of the UIDs/names.

I.e. if a UID is in the pool, it won't be used unless for the specific name in
the pool.

Attached is a patch that accompilshes this. The RESERVE_UID_POOL and
RESERVE_GID_POOL configurations can be used to enable/disable this feature.

This could also be used to solve bug 248500.

Thanks,
    Yair.
