Jörg Thalheim c9c8a2c5b3 nixos/memcached: make unix sockets usuable
before:
  - /var/run/memcached is a bad default for a socket path, since its
    parent directory must be writeable by memcached.
  - Socket directory was not created by the module itself -> this was
    left as a burden to the user?
  - Having a static uid with a dynamic user name is not very useful.

after:
  - Replace services.memcached.socket by a boolean flag. This simplifies
    our code, since we do not have to check if the user specifies a
    path with a parent directory that should be owned by memcached
    (/run/memcached/memcached.sock -> /run/memcached).
  - Remove fixed uid/gid allocation. The only file ever owned by the
    daemon is the socket that will be recreated on every start.
    Therefore user and group ids do not need to be static.
  - only create the memcached user, if the user has not specified a
    different one. The major use case for changing option is to allow
    existing services (such as php-fpm) opening the local unix socket.
    If we would unconditionally create a user that option would be
    useless.

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:

% git remote add channels git://github.com/NixOS/nixpkgs-channels.git

For stability and maximum binary package support, it is recommended to maintain custom changes on top of one of the channels, e.g. nixos-17.09 for the latest release and nixos-unstable for the latest successful build of master:

% git remote update channels
% git rebase channels/nixos-17.09

For pull-requests, please rebase onto nixpkgs master.

NixOS Linux distribution source code is located inside nixos/ folder.
