hi i use flakes and so i'm stuck needing a version 2.18.1 because my flakes all have 'lastModified' attrib in them and 2.17 won't use that. i can nix run nix/nix, for temporary uses, but i can't actually run my normal flakes or nixos build because i can't figure out how to install a different version. the file system is readonly is the error i get, or if i install it using overlay it just doesn't seem to get used. |

my question is how can i install a different version? or can we get the base version updated? the nix.dev script fails for readonly, and my limited understanding hasn't allowed me to force it using my configuration.nix. i can kind of understand how i could maybe do this if i upgraded to 2.17 flakes, then switched my nix package using flakes, then upgraded to my 2.18 flakes with lastModified attrib? |
