Is there a way to run a command after creating a filesystem with disko?
I want to run mkdir $target/{home,nix} to allow these directories binding to their real locations, e.g. something like this

fileSystems."/nix" = {
	device = "/persist/nix";
	fsType = "none";
	options = [ "bind" ];
	depends = [ "/persist" ];
	neededForBoot = true;
};

did you figure this one out? im trying to do exactly what youre doing right now, i need to setup a bind mount /nix -> /persist/nix

    nodev."/nix" = {
      fsType = "ext4";
      device = "/dev/disk/by-id/ata-SK_hynix_SC311_SATA_128GB_MJ88N52701150940J-part3";
      mountOptions = [
        "X-mount.subdir=nix"
      ];
      preMountHook = ''
        tmpdir=$(mktemp -d)

        mount /dev/disk/by-id/ata-SK_hynix_SC311_SATA_128GB_MJ88N52701150940J-part3 $tmpdir
        mkdir $tmpdir/nix
        umount $tmpdir
      '';
    };

jfc way too complex

hmm, maybe not implemented yet

thats also a valid way, i did it slightly differently

In reply to@magic_rb:matrix.redalder.org

    nodev."/nix" = {
      fsType = "ext4";
      device = "/dev/disk/by-id/ata-SK_hynix_SC311_SATA_128GB_MJ88N52701150940J-part3";
      mountOptions = [
        "X-mount.subdir=nix"
      ];
      preMountHook = ''
        tmpdir=$(mktemp -d)

        mount /dev/disk/by-id/ata-SK_hynix_SC311_SATA_128GB_MJ88N52701150940J-part3 $tmpdir
        mkdir $tmpdir/nix
        umount $tmpdir
      '';
    };

jfc way too complex

Even today I still get

++ mkdir -p /mnt/nix/store
++ xargs cp --recursive --target /mnt/nix/store
cp: cannot access '/nix/store/jdrm9vk8z5lixyaalnl61wy2gjw64l3h-kmod-blacklist-31+20240202-2ubuntu8': Cannot allocate memory

on the latest disko
