Yup. That's correct. I am asking about how to modify
set root=(hd0,msdos1) (I think this is the vfat system)
chainloader (${root})/efi/boot/name-of-efi-file.efi
boot
to something like
set root=(hd0,msdos1) (I think this is the vfat system)
chainloader (${root})/efi/boot/name-of-efi-file.efi
linux (hd0,msdos1)/path/to/vm-linuz-libre ?
boot
But thanks for reminding me about disabling modesetting. If I can't boot the
usbstick via modesetting, then I probably need to change my config to disable
it as well. Otherwise I'll successfully install guixSD and grub, but the boot
process will fail when it tries to load the raedon driver.
Don't worry too much about trying to find a solution for me. Worst case
scenerio, I think that I can unstill grub. Install systemd-boot again, modify
the boot parameters via systemd-boot boot menu, boot guixSD from the usb stick.
Uninstall systemd-boot, install grub, and reboot and we should be
golden....But If I can figure out how to just use grub properly, that'd be
nicer. haha. I think grub comes with a search command, but I haven't really
figured out how to use it, and that search command may just be for finding the
root filesystem.

The kernel arguments should go into the operating system configuration
file. There’s a field “kernel-arguments”, which is just a list of
strings.
Here’s an example:
--8<---------------cut here---------------start------------->8---
(operating-system
…
(kernel-arguments
'("iomem=relaxed" ; Needed for using flashrom
"zswap.enabled=1" ; compressed RAM cache for swap devices
"vm.swappiness=100" ; NOTE: only use this with zswap!
))
…)
--8<---------------cut here---------------end--------------->8---
BUT I don't know where the linux kernel is on the usbstick.
Oh, this is still about booting the USB image? The comment above is
about how to add extra arguments once you’ve already installed GuixSD.
