Consider example:
$ nix-instantiate ./nixos -A system --arg configuration '
{
boot.isContainer = true;
nixpkgs.overlays = [ (self: super: {
nix = self.pkgsStatic.nix;
}) ];
}'
When resolving package through overlays, we figure out that
nix == self.pkgsStatic.nix
=>
nix == (import <nixpkgs> { inherit overlays; }).nix
=>
nix == (import <nixpkgs> { overlays = [(self: super: { nix = self.pkgsStatic.nix; })];}).nix
and we enter infinite recursion of nixpkgs evaluations.
The proper fix should terminate recursion by assigning self fixpoint
to inner custom package set. But I get infinite recursion somehow, so
I use `super`. It is less correct modulo deep custom overrides, but behaves
correctly for simple cases and doesn't OOM evaluator.

This rare sitation was caught when building zoom-us package:
```
automatically fixing dependencies for ELF files
/nix/store/71d65fplq44y9yn2fvkpn2d3hrszracd-auto-patchelf-hook/nix-support/setup-hook: line 213: echo: write error: Broken pipe
/nix/store/71d65fplq44y9yn2fvkpn2d3hrszracd-auto-patchelf-hook/nix-support/setup-hook: line 210: echo: write error: Broken pipe
```
The worst is that derivation continued and resulted into broken package:

I hope, replacing `grep -q` with `grep` will remove this race condition.
The explicit remove helped to uncover some hidden uses of `optionSet`
in NixOps. However it makes life harder for end-users of NixOps - it will
be impossible to deploy 19.03 systems with old NixOps, but there is no
new release of NixOps with `optionSet` fixes.
Also, "deprecation" process isn't well defined. Even that `optionSet` was
declared "deprecated" for many years, it was never announced. Hence, I
leave "deprecation" announce. Then, 3 releases after announce,
we can announce removal of this feature.
This type has to be removed, not `throw`-ed in runtime, because it makes
some perfectly fine code to fail. For example:
```
$ nix-instantiate --eval -E '(import <nixpkgs/lib>).types' --strict
trace: `types.list` is deprecated; use `types.listOf` instead
error: types.optionSet is deprecated; use types.submodule instead
(use '--show-trace' to show detailed location information)
```
ryantm bot updates `psqlSchema` alongside with version: https://github.com/NixOS/nixpkgs/pull/50646, https://github.com/NixOS/nixpkgs/pull/55860
but `psqlSchema` is used to generate `stateDir`. It shouldn't be updated.
Ideally it should be equal to postgresql major version for pg versions,
but we already have deployments in /var/lib/postgresql/11.1. Strange why
nobody complained when it was changed from 11.0 -> 11.1.
I propose do correct naming for PG12+, but status quo for current versions.

postgis: cleanup
Another part of https://github.com/NixOS/nixpkgs/pull/38698, though I did cleanup even more.
Moving docs to separate output should save another 30MB.
I did pin poppler to 0.61 just to be sure GDAL doesn't break again next
time poppler changes internal APIs.
* postgresql: reorganize package and it's extensions
Extracts some useful parts of https://github.com/NixOS/nixpkgs/pull/38698,
in particular, it's vision that postgresql plugins should be namespaced.
This creates a dependency cycle when used with boot.tmpOnTmpfs:
basic.target <- tmp.mount <- swap.target <- zram-init-dev0 <- basic.target
This same fix is done already for tmp.mount
Fixes https://github.com/NixOS/nixpkgs/issues/47474
- 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
```
Fake hashes can be used as placeholders for all the places, where
Nix expression requires a hash, but we don't yet have one.
This should be more convenient than following:
- echo|sha256sum, copy into clipboard, go to editor, paste into previously
edited place
- search nixpkgs for a random package, copy it's hash to cliboard, go to
editor, paste into previously edited place
Nix can add support for these fake hashes. In that case printed error should contain
only 1 hash, so no more problem "which of two hashes from error should I use?"

Qt 5.11 was downgraded to 5.9 because of two issues:
- spawns errors like

- Google login doesn't work. It just doesn't start embedded webbrowser
Apart from version update:
- remove some packages from `LD_LIBRARY_PATH`. I haven't found any
references for them. Most of them were copypasted from AUR expression
- found an implicit reference to `pidof`, in my case this caused warnings
about mismatched Glibc version. I've found implicit reference to `sh` too,
with Glibc warning too, but I don't know how to fix this, and looks like it's
only a warning
Comparing packages via equality will lead to different results when package and module are from different
`nixpkgs` checkouts.
Also, because MariaDB is actually supported, added a note to option description to make this knowledge more discover-able.
In particular, it conflicts with `services.tlp.enable` option.
There exists workaround:
```
powerManagement.cpuFreqGovernor = lib.mkForce null;
services.tlp.enable = true;
```
But should it?
* readme.md: reincarnate wiki
It is kinda strange to announce that wiki is deprecated, while it is in fact growing.
I'd say, the "Move-the-wiki" milestone is stalled instead.
* Readme.md: rename to community maintained wiki
Container config example code mentions `postgresql` service, but the correct use of that service involves setting `system.stateVersion` option (as discovered in https://github.com/NixOS/nixpkgs/issues/30056).
The actual system state version is set randomly to 17.03 because I have no preferences here
The libcrypto patch didn't work well with `salt-ssh` (that code failed on
remote machines), so let's make Nix-based library lookup as fallback.

Webcam Logitech C270 showed black screen in zoom, but LD_PRELOADing
v4l1compat.so fixed this. I hope, this wouldn't break camera for people,
who were already able to see video, but I can't be 100% sure currently.
Turns out, zoom couldn't launch QtWebEngineProcess because of wrong interpreter
Also, there was a need for some extra deps, which I found when
running debug version of zoom.
This allows to scroll content in less, screen, nano, tmux and others
(the ones, who create so called "secondary screens"), similar to VTE-based
terminals.
Note, however, that mouse wheel won't work in `less -X`, which is used
by basic `journalctl`. Fix it with `export SYSTEMD_LESS=FRSMK`
The `groups.1.gz` collides with one from coreutils. The code to fix this
was already present in expression, but wrongly assumes that share/man/man1
directory will be copied to `man` output after `installPhase`.
It turned out, that man directory is set at configure step, so we should
remove file from `man` output.
