rewritten to match void's documentation style, please check that I didn't mess up anything

[dkwo]

I would not have dropped the reference to payload variable, in case someone does not want to use uboot+grub.

[classabbyamp]

in what cases would you want to use the kernel payload? even if not using grub, it seems that you'd typically want to use u-boot with whichever bootloader/uki

also, is --removable for grub required or recommended?

Required. There is no access to efivars, and m1n1 only knows how to execute the hardcoded $ESP\EFI\BOOT\BOOTAA64.EFI

[dkwo]

m1n1 can take kernel+initramfs+dtbs as payload, that's the meaning of payload=kernel: this does not use grub, nor uboot, and does not require any hardcoded $ESP\EFI\BOOT\BOOTAA64.EFI or similar. @Calandracas606 Not sure why you think that. (dtbs are taken from kernel btw, not uboot). m1n1 is the bootloader, in some sense.

As for grub, I only meant that --removable works for me. Did not mean it is required. I'm not an experienced grub user, but by simply looking at https://github.com/AsahiLinux/asahi-scripts/blob/main/update-grub in asahi-scripts it seems clear that one can configure grub properly, without using --removable (at least it's not mentioned there).

Quick question: currently on these machines

$ xuname 
Void 6.12.10+2-asahi_2 aarch64 Unknown uptodate rFFFF

Would it make sense to use something like

$ cat /proc/device-tree/model 
Apple MacBook Air (M1, 2020)

for CPU?

[classabbyamp]

bring it up in leahneukirchen/xtools#227 i guess

[classabbyamp]

(at least it's not mentioned there).

https://github.com/AsahiLinux/asahi-scripts/blob/main/update-grub#L28
https://github.com/AsahiLinux/asahi-scripts/blob/main/update-grub#L77

this is equivalent to grub-install --removable

[dkwo]

Thanks for clarifying that they are equivalent to --removable.
The current text looks good to me.
