Hi - I've found at least one race condition in the adduser script on Ubuntu 18.
The program searches for an available UID (and GID), then adds the new user with the selected UID/GID numbers without any synchronization, so two near-simultaneous invocations of the program can produce two users with identical GIDs (what I saw), or, presumably, identical UIDs. Is there a bug/issue tracker somewhere for this program? agape brent
