I need to add some specific boot options, in my case it’s mem_sleep_default=deep
I can add this to the /boot/loader/entries/ file but this seems to get regenerated when I upgrade (kernel or systemd, not figured it out yet).
What is the precursor to that file? If this was grub, I’d change the grub.cfg.
Is there an equivalent for systemd-boot?
Thank you in advance!
