L0.0ks interesting thanks for the link !
In the past i did some messing about
applying this ( stage-1-init: add support for the ability of specify a name of squashfs image)
https://github.com/NixOS/nixpkgs/pull/9722 now closed PR / patch
This option makes for easy testing different squashfs from same disk\partition .
So now im wondering how easy would it be to
apply this patch
create a ./bin/make-squashfs to output only a nix#name.squashfs initrd#name.lz kernel#name
hopefully the above make sense xD
for the curious cats i found some of the magic resides @
Could this be used to generate a smaller PXE image to boot on computers with not enough RAM for the normal PXE image?
Lasselus is currently working on netboot images: https://github.com/NixOS/nixos-channel-scripts/pull/21#issuecomment-454874956 They are still based on our iso, which is rather large. I think your best shot would be to build an initrd that mounts nixos via nfs.
