This should be documented somewhere (probably the installation section of the manual). |
|
works snappy with the following boot option: {
boot.kernelParams = [ "copytoram=1" ];
} |
|
a 2nd boot option could also be added here: https://github.com/NixOS/nixpkgs/blob/master/nixos/modules/installer/cd-dvd/iso-image.nix#L33 then the user would have a choice at boot time |

This change adds the possibility for the copytoram kernel parameter. If supplied the whole image is loaded into a tmpfs during stage-1. Afterwards a removal of the USB-device/CD is possible without the system breaking.
