From Fedora Project Wiki
halt, poweroff, reboot Configuration Moved
The ability to use halt(8), poweroff(8) and reboot(8) commands by unprivileged users is now controlled using polkit
, see the actions in /usr/share/polkit-1/actions/org.freedesktop.login1.policy
. The PAM configuration files /etc/pam.d/{halt,poweroff,reboot}
are no longer used and their content, if any, is ignored.
