aarch64 build on aarch64 linux fails with, no idea fixed

[mkg20001]

fixed build failures. works now on aarch64 aswell. failure was caused by NixOS/nixpkgs#145726

[Mic92]

Is this a profile like qemu-guest.nix in nixpkgs/nixos? I have the feeling we can just add this to nixpkgs directly. Than also all dependencies would be build in Hydra.

[mkg20001]

@Mic92 yes. I added it to nixos-hardware, since building the packages is a bit hacky for now. Or do you think this looks good enough for upstream?

[mkg20001]

current issue: /dev/vsock is missing, which forwarder_guest_launcher needs. it crashes with file not found error. (At leadt i think its that file, last thing in strace) fixed

[mkg20001]

Currently the partition ids are deterministic. The terminal app has a feature where in case something goes wrong and the system can't boot, the system can be reinstalled and the previous one made available under /dev/vdb

If I understand correctly, this brings the issue of having two partitions with the same ids at the same time.
