# Artefacts
-If you don't want to use the prebuild artefacts, you can build them yourself using the [bootstrap.sh](https://git.zerfleddert.de/cgi-bin/gitweb.cgi/m1-debian/blob_plain/refs/heads/master:/bootstrap.sh) script.

# Asahi installer
* Configure wifi by editing the wpa_supplicant.conf, enabling the interface and remove the # before allow-hotplug to enable it during boot.
vi /etc/wpa_supplicant/wpa_supplicant.conf
- ifup wlp1s0f0
+ ifup wlan0

* Reboot to see if grub was correctly installed
* Install a desktop environment for example blackbox
+ apt-get update
apt-get install -y xinit blackbox xterm firefox-esr lightdm
* Create yourself an unprivileged user

But if you know how to do that, you probably don't need this guide.
- If possible use an Ethernet Dongle, less typing.

In order to format the usb stick under Macos, open the disk utility, right-click on the usb stick (usually the lowest device in the list) and select erase. Choose the following options:
* You need to run the asahi installer and have either an OS installed or m1n1+UEFI.
-* If you have a EFI binary on the NVMe and want to boot from the usb stick, you need to interrupt u-boot on the countdoun by pressing any key and run the following comamnd to boot from usb:

# FAQ
-* If I install Debian, will it still be relatively easy to update the Asahi work as it develops?
+## How to enable spakers?
+
+Currently speakers are only supported on M1 air. Install the necessary packages:
+
+ apt update
+ apt upgrade -y
+ apt dist-upgrade -y
+ apt install -y alsa-ucm-conf-asahi speakersafetyd
+ reboot
+
+After the reboot I need to restart the speakersafetyd in order to hear sound out of the speakers:
+
+ sudo systemctl restart speakersafetyd
+
+## Does it work on M2?
+
+Yes, M3 is not yet supported.
+
+## Are you still maintaining this?
+
+Yes, I do and will continue doing this until there is an official Debian installer.

+## If I install Debian, will it be easy to update the Asahi work as it develops?
Yes, long answer below.
To update the kernel to the lastest "stable" asahi branch you need to run
as root:
- curl -sL https://tg.st/u/ksh | bash
+ apt update
+ apt upgrade
+
+For installations before 2022-12-12, see <https://thomas.glanzmann.de/asahi/README.txt>

+Later it might be necessary to upgrade the stub partion in order to
support the GPU code. As soon as that happens, I'll add the
instructions and a video in order to do so, but short version is:
So, you never need to reinstall Debian. Kernel updates are easy, stub
updates are a little bit more cumbersome but also seldom.

+## How do I compile zfs on apple silicon debian?
+
+- In order to build zfs you need the rust environment. So from the m1-debian
+ repository you have to run these scripts:
+
+ ./dependencies.sh
+ ./prepare_rust.sh
+
+- Prepare your zfs build environment. You need to replace
+ /home/sithglan/work/m1-debian with your path to
+ your m1-debian checkout:
+
+ export CARGO_HOME="/home/sithglan/work/m1-debian/build/cargo"
+ export RUSTUP_HOME="/home/sithglan/work/m1-debian/build/rust"
+ source "/home/sithglan/work/m1-debian/build/cargo/env"
+
+- You have to specify the default rust version:
+
+ rustup default 1.68.2
+
+- Tell zfs which version of clang you use to compile the kernel:
+
+ export KERNEL_LLVM=-15
+
+- Checkout ZFS:
+
+ git clone https://github.com/openzfs/zfs
+ cd ./zfs
+ git checkout master
+
