Hello,
I modified the daily build of d-i to be able to install it on m1.
Currently I have the following problems:
- I need to extract some wifi firmware from a usb stick
- I need to tell grub to use the removable media path and not
try to update the nvram
- The signed grub binary should not be installed because u-boot
hangs when it tries to load the same.
- I need to install a custom kernel
I tried three things:
- Create a preseed.cfg in the root of the initramfs with the
following options:
d-i base-installer/kernel/image string none
d-i preseed/early_command /wifi.sh
d-i preseed/late_command /kernel.sh
grub-efi-arm64 grub2/update_nvram boolean false
grub-efi-arm64 grub2/force_efi_extra_removable boolean true
When I do that the debian installer does not start on vt0, I
have to go to vt1 and attach to a screen session with a
basic d-i in it. I want the regular one.
- Tried the hooks here: https://d-i.debian.org/doc/internals/apb.html
/usr/lib/debian-installer-startup.d/
This directory did not exist, I created it, but the script was
not executed.
/usr/lib/post-base-installer.d/*
This is the only hook that worked for me. But I tried to use it
to set the following two options in /target system which were
ignored when installing grub:
grub-efi-arm64 grub2/update_nvram boolean false
grub-efi-arm64 grub2/force_efi_extra_removable boolean true
/usr/lib/finish-install.d/* [finish-install]
This script was not executed.
- So what I now did is write two scripts which are being
executed by the user on a shell on the first installer page to
load the wifi firmware. And when grub installation failed to
install grub and install a kernel.

If you have any advise for me how to improve the procedure, so that the
user does not need to install the scripts manually, please let me know.
Cheers,
Thomas
