[arch-dev-public] [signoff] shadow-4.1.4.2-2 - was: Fixing groupadd

Signoff shadow. Fixes always creating system groups with ID 99 (FS#16092). Now UID/GIDs are as follows: 0-499 -> reserved for Arch packaging 500-999 -> system users/groups 1000-60000 -> general users/groups. For some reason "groupadd --system" starts adding groups at 999 and working down, but that appears an upstream decision. Signoff both, Allan
