Commit 9bfe92ecee ("docker: Minor improvements, fix failing test") added the services.docker.storageDriver option, made it mandatory but didn't give it a default value. This results in an ugly traceback when users enable docker, if they don't pay enough attention to also set the storageDriver option. (An attempt was made to add an assertion, but it didn't work, possibly because of how "mkMerge" works.) The arguments against a default value were that the optimal value depends on the filesystem on the host. This is, AFAICT, only in part true. (It seems some backends are filesystem agnostic.) Also, docker itself uses a default storage driver, "devicemapper", when no --storage-driver=x options are given. Hence, we use the same value as default. Add a FIXME comment that 'devicemapper' breaks NixOS VM tests (for yet unknown reasons), so we still run those with the 'overlay' driver. Closes #10100 and #10217.

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-15.09
for the latest
release and nixos-unstable
for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-15.09
For pull-requests, please rebase onto nixpkgs master
.
NixOS linux distribution source code is located inside
nixos/
folder.
