Re: grub not properly installing in GuixSD

[Joshua Branson]

     So some new updates:


I can properly boot guixSD in UEFI from the grub command prompt! Aka I 
chainload the operating system.  Unfortunately I do not know how to 
chainload the OS and pass a kernel argument.  I need to pass nomodeset.

So I booted GuixSD in UEFI mode via (I'm writing from memory.  I think 
this is the command I used):


set root=(hd0,msdos1)    (I think this is the vfat system)

chainloader (${root})/efi/boot/name-of-efi-file.efi

boot


Now the guixSD image boots just fine, BUT it fails when it tries to load 
in raedon driver.  Is there a way to specify linux kernel boot 
parameters?  Apparently you can when you load the kernel. aka linux 
(hd0,1)/path-to-linux nomodeset


BUT I don't know where the linux kernel is on the usbstick.
