Problem is that i need to push text string into driver_override on pci bus, before driver has been loaded.
I did solve this using systemd earlier, but after a update driver loads before systemd even starts so no luck there.
Also driver doesn't support unbinding.
Any ideas ?
You can add an
init=</full/path/to/script> kernel parameter to your kernel cmdline to run your script instead of systemd's init. Then launch systemd's init from your script.
