danbst 8d8a7210e4 zramSwap: allow configure compression algorithm + cleanups 
- add `zramSwap.algorithm` option, which allows to change compressor
declaratively. zstd as default
- add `zramSwap.swapDevices` option, which allows to define how many zram
devices will be used as swap. Rest devices can be managed freely
- simpler floating calculations
- fix udev race condition
- some documentation changes
- replaced `/sys/block/zram*` handling with `zramctl`, because I had occasional
"Device is busy" error (looks like zram has to be configured in predefined order)
- added `memoryPercent` and `algorithm` as restart triggers. I think, it was
a bug that changing `memoryPercent` in configuration wasn't applied immediately.
- removed a bind to .swap device. While it looks natural (when swap device goes
off, so should zram device), it wasn't implemented properly. This caused problems
with swapon/swapoff:
```
$ cat /proc/swaps
Filename                                Type            Size    Used    Priority
/dev/zram0                              partition       8166024 0       -2
/var/swapfile                           file            5119996 5120    1

$ sudo swapoff -a

$ sudo swapon -a
swapon: /dev/zram0: read swap header failed

$ cat /proc/swaps
Filename                                Type            Size    Used    Priority
/var/swapfile                           file            5119996 0       1
```

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 https://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-18.09 for the latest release and nixos-unstable for the latest successful build of master:

% git remote update channels
% git rebase channels/nixos-18.09

For pull requests, please rebase onto nixpkgs master.

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