hi if i manually edit UIDs and GIDs in /etc/passwd, /etc/group will that cause any problems? for instance if i have a user with UID and GID of 515/515 and then change it to 510/510. i'm just curious since i have deleted some users and there where some "free" UIDs and GIDs so to make it look better i thought of changing them so it goes from 500-510... another reason is that i'm going to install a new server and move users from the old server to new server (preserving userdata and passwds etc) so i though this may be a reasonable time to clean up users that is no longer in use. øyvind
