Description Mauro Matteo Cascella 2022-09-26 15:15:17 UTC 
When the redfish plugin automatically creates an OPERATOR user account on the BMC we save the autogenerated password to /etc/fwupd/redfish.conf, ensuring it is chmod'ed to 0660 before writing the file with g_key_file_save_to_file(). The GLib in RHEL 9 versions instead calls g_file_set_contents_full() with the mode hardcoded to 0666, which undoes the previous chmod().
