This takes another approach at binding FHS directory structure. We now bind-mount all the root filesystem to directory "/host" in the target tree. From that we symlink all the directories into the tree if they do not already exist in FHS structure. This probably makes `CHROOTENV_EXTRA_BINDS` unnecessary -- its main usecase was to add bound directories from the host to the sandbox, and we not just symlink all of them. I plan to get some feedback on its usage and maybe deprecate it. This also drops old `buildFHSChrootEnv` infrastructure. The main problem with it is it's very difficult to unmount a recursive-bound directory when mount is not sandboxed. This problem is a bug even without these changes -- if you have for example `/home/alice` mounted to somewhere, you wouldn't see it in `buildFHSChrootEnv` now. With the new directory structure, it's impossible to use regular bind at all. After some tackling with this I realized that the fix would be brittle and dangerous (if you don't unmount everything clearly and proceed to removing the temporary directory, bye-bye fs!). It also probably doesn't worth it because I haven't heard that someone actually uses it for a long time, and `buildFHSUserEnv` should cover most cases while being much more maintainable and safe for the end-user. |

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-16.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-16.03
For pull-requests, please rebase onto nixpkgs master.
NixOS linux distribution source code is located inside
nixos/ folder.
