systemd | adding permanently specific command

hey guys,

i installed archlinux with the archinstaller and selected the systemd bootloader with unified kernel.
Now i want to add the following command (as far as i know in mkinitcpio early init environment) but i couldn't manage it:
amdgpu.ppfeaturemask=0xffffffff
it seems i cant really find the file / hook / whatever where i extend the line. In the past i mostly used grub, but this time i wanted something else

hope you can help me.
Thank you so much in advance.

If you had installed manually you would already have known this.

EDIT: actually that's probably not right for a UKI. I have no idea how archinstall sets that up though. If you share the install log it will probably show the details. Hopefully.

Re: systemd | adding permanently specific command

Did you check /var/log/archinstall?

Re: systemd | adding permanently specific command

https://man.archlinux.org/man/loader.conf.5.en#OPTIONS

The configuration options supported by ESP/loader/entries/*.conf and XBOOTLDR/loader/entries/*.conf files are defined as part of the Boot Loader Specification[1].

https://uapi-group.org/specifications/s … ification/ - scroll a bit up if you're unclear what the .conf files name should be.

but yea exactly this is my "problem" ^^

So you've seen the error of your ways…

That makes no sense

Please post the output of

cat /var/log/archinstall/*

Do you have a file at /etc/kernel/cmdline? That might be the key here.

Re: systemd | adding permanently specific command

Assuming the UKI is generated by mkinitcpio, you can either use *.conf files in /etc/cmdline.d/, or use /etc/kernel/cmdline, see: https://wiki.archlinux.org/title/Unifie … mmand_line

Re: systemd | adding permanently specific command

Edit: with the modification in /etc/kernel/cmdline it works like a charm. Thank you so much.

This should be the main file, if anyone else use the archinstaller with UKI.
