Ensure default group for the root account is GID 0

SrednjaNivo 1Automatskacos

Opis

The usermod command can be used to specify which group the root user belongs to. This affects permissions of files that are created by the root user. Using GID 0 for the root account helps prevent root -owned files from accidentally becoming accessible to non-privileged users.
