I have a surface go 3 and a surface pro 7. I installed Arch on both and also enabled secure boot. Installing Arch works, but wifi on the installation drive doesn’t work. I plug in a usb hub with Ethernet and I’m fine after. Enabling secure boot is harder, but it can work.
That is cool. I use dcli which is quite nice to use and easily manages dotfiles and scripts. I see you’ve added post install hooks which would allow to manage dotfiles for example.
I really like to use a declarative package manager on a different distro than NixOS. My current install is managed entirely by that tool with specific scripts that modify some config files like fstab for instance.
