Preset all systemd units on first boot

On a Fedora system you booted from an image without the fully populated /etc/ directory (First Boot), systemd will execute an equivalent of the systemctl preset-all command. As a result, units will be enabled or disabled according to the preset configuration.

The systemd service manager will disable any units, to which you manually created symbolic links against the preset rules.

You can use the systemctl preset-all command at any time to apply the preset configuration. If you did not make any prior local changes to the configuration, the command would make no changes to unit state. If you enabled or disabled some units, the command would return unit enablement to the after-installation pristine state.
