cupsd compares directive names with _cups_strcasecmp, so a hand-edited "systemgroup sys root wheel" is live configuration, but matching $1 against the canonical spelling skipped it and appended a second directive at the end of the file. parse_groups accumulates the groups of every SystemGroup directive it reads rather than replacing them, so both lines took effect and wheel kept the passwordless administration this is meant to remove, with the migration reporting success.

The migration recomputed whether cups-browsed was active at the start of every run, after an earlier run may already have stopped it. A run interrupted between that stop and the completion marker left the service down, and the retry that followed read it as inactive, skipped the restart, and wrote the marker anyway: printer discovery stayed off until the next reboot with no migration left to bring it back. Keying the restart to whether the unit is enabled survives the interruption, and reports not-enabled for a unit the user masked or disabled, which restarting would fail on and abort the migration short of its marker.

Run cups-browsed as a locked service account with a dedicated cache and a focused systemd sandbox. Restrict automatic queues to driverless IPP printers, remove wheel from passwordless CUPS administration, replace cups-pdf with Polkit-backed setup, and migrate existing systems safely.
