I am trying to migrate from Ubuntu to Fedora, so I am not fully familiar with fedora specifics yet.

I am trying to setup a kernel parameter at boot time.

I am looking for a "default" or equivalent file, so that the setting persists after kernel updates, etc.

My expectation is that I will add a default setting, and run a script that will update the boot sector/files.

Googling around I can find references to Grub2 and the /etc/default/grub file.

However, I dont think my system comes with Grub/2 at all, but rather extlinux.

I can find the extlinux configuration files, but I have no idea how was generated or where the settings come from.

How is this done with Fedora?

Thanks, I can change parameters of the currently configured kernel with gubby --extlinux --args=... --updae-kernel=all. The remaining question is what will happen once a new kernel is installed by the update subsystem. Will it also apply my configured arg?
