* refactor and clean up the derivation composition
* add slim variation: the slim variations configure node without npm.
Building node with npm introduces a python runtime depndency through
gyp - slim variation makes sense for building small nodejs production
images
This commit should fix the package building to build due to https://github.com/NixOS/nixpkgs/issues/16238
Printing tested on M2875FD and M2675FN models. Scanning not tested yet due to lack of access of Samsung scanning devices.
All work in this commit is attributed to @jokogr. Content of this commit is basically copied+pasted from c41e771a38
In the prestart config of the smokeping service, smokeping is executed
initially. This happens as the user root and writes some files to
$smokepingHome, which can't be overwritten by the smokeping user. This
gives an error message.
I fixed this by moving the chown step after the initial smokeping runs,
so that it also affects the generated files.
The matrix-synapse user has `createHome = true;` which runs before the
`preStart` script, so the home directory will always exist and the block
will never execute.
Also don't include default path to keys in the configuration file,
because synapse will choke if it tries to open them before they
exist (even with `--generate-keys`).
This commit changes callHackage to use a deterministic version of the Hackage
checkout from https://github.com/commercialhaskell/all-cabal-hashes by default.
This means that packages uploaded to Hackage after today will be available to
callHackage only after "pkgs/data/misc/hackage/default.nix" has been updated.
People who want the previous behavior where we always had the latest version of
Hackage available -- at the cost of frequent downloads from Github --, can add
the following override to their "~/.nixpkgs/config.nix" file:
{
packageOverrides = super: {
all-cabal-hashes = builtins.fetchTarball "https://github.com/commercialhaskell/all-cabal-hashes/archive/hackage.tar.gz";
};
}
Presumably, readline used to be propagated from one of the other inputs
but is no longer (the build succeeds on 16.09 but is unable to locate
readline.h on master).
