# This option defines the first version of NixOS you have installed on this particular machine,

#
# Most users should NEVER change this value after the initial install, for any reason,
# even if you've upgraded your system to a new NixOS release.
#
# This value does NOT affect the Nixpkgs version your packages and OS are pulled from,
# so changing it will NOT upgrade your system - see https://nixos.org/manual/nixos/stable/#sec-upgrading for how
# to actually do that.
#
# This value being lower than the current NixOS release does NOT mean your system is
# out of date, out of support, or vulnerable.
#
# Do NOT change this value unless you have manually inspected all the changes it would make to your configuration,
# and migrated your data accordingly.
