I've noticed that GRUB2 on Fedora uses BootLoaderSpec (see this page: https://fedoraproject.org/wiki/Changes/BootLoaderSpecByDefault ), however, if you (or an RPM scriptlet) uses the 'grubby' command to change the kernel parameters, in the individual /boot/loader/entries/ files, the 'options $kernelopts' line is replaced with the full kernel options, and they're never updated again even if you change the /etc/default/grub settings. FWIW, the nvidia packages use grubby in an RPM post script, so people who use those often run into this. It looks like this has been reported: https://bugzilla.redhat.com/show_bug.cgi?id=1651686 I'm not sure if Fedora needs to do a better job documenting this behavior, or if it should just be fixed so people aren't confused by this. Maybe something like "These settings only affect when the system is loaded and changing them won't affect a running system's grub" in the /etc/default/grub file?
