Alpine's built-in 'users' group owns GID 100 and 'nobody' owns UID 99. The old check tested by name (appgroup/appuser) which always passed, then hit 'addgroup: gid 100 in use' on creation. Now checks by GID/UID via getent — reuses the existing group/user if the ID is already taken, only creates new ones when the ID is free. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
