 Yes, long answer below.
 
 To update the kernel to the lastest "stable" asahi branch you need to run

+## 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
+
+- Build a kernel that is not cross compiled. Because the cross compiled header
+  package does contain the fixtool for the wrong architecture at the moment and
+  install the resulting kernel deb and headers and boot into it:
+
+        ./m1n1_uboot_kernel.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
+
