The motivation for this is that some applications are unaware
of this feature and can set their volume to 100% on startup
harming people ears and possiblly blowing someone's audio
setup.
I noticed this in #54594 and by extension epiphany[0].
Please also note that many other distros have this default for
the reason outlined above.

- 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
```
Since nix 2.0 the no-build-hook option was replaced by the builders options
that allows to override remote builders ad-hoc.
Since it is useful to disable remote builders updating nixos without network,
this commit reintroduces the option.
This adds a NixOS option for setting the CPU max and min frequencies
with `cpufreq`. The two options that have been added are:
- `powerManagement.cpufreq.max`
- `powerManagement.cpufreq.min`
It also adds an alias to the `powerManagement.cpuFreqGovernor` option as
`powerManagement.cpufreq.governor`. This updates the installer to use
the new option name. It also updates the manual with a note about
the new name.
Having pam_unix set to "sufficient" means early-succeeding account
management group, as soon as pam_unix.so is succeeding.
This is not sufficient. For example, nixos modules might install nss
modules for user lookup, so pam_unix.so succeeds, and we end the stack
successfully, even though other pam account modules might want to do
more extensive checks.
Other distros seem to set pam_unix.so to 'required', so if there are
other pam modules in that management group, they get a chance to do some
validation too.
For SSSD, @PsyanticY already added a workaround knob in
https://github.com/NixOS/nixpkgs/pull/31969, while stating this should
be the default anyway.
I did some thinking in what could break - after this commit, we require
pam_unix to succeed, means we require `getent passwd $username` to
return something.
This is the case for all local users due to the passwd nss module, and
also the case for all modules installing their nss module to
nsswitch.conf - true for ldap (if not explicitly disabled) and sssd.
I'm not so sure about krb5, cc @eqyiel for opinions. Is there some nss
module loaded? Should the pam account module be placed before pam_unix?
We don't drop the `security.pam.services.<name?>.sssdStrictAccess`
option, as it's also used some lines below to tweak error behaviour
inside the pam sssd module itself (by changing it's 'control' field).
This is also required to get admin login for Google OS Login working
(#51566), as their pam_oslogin_admin accounts module takes care of sudo
configuration.
pkgs.owncloud still pointed to owncloud 7.0.15 (from May 13 2016)
Last owncloud server update in nixpkgs was in Jun 2016.
At the same time Nextcloud forked away from it, indicating users
switched over to that.

This fixes some quirks I introduced in previous commits.
1. No need for an extra newline when printing the output of shell commands.
2. 'or die' is what's already used in the NixOS test sources, while
'die unless' has no occurrences.

TrueCrypt has been retired for a while now and the source archive we
pointed to is gone. Moreover the VeraCrypt fork is available, maintained
and fixes issues previous audits found in TrueCrypt.
Nixpkgs' channel currently can't move forward so long as there is a
trace in evaluating the top-level arguments. Which means that it isn't
possible to add a warning message to warn users of future package
removal.
So the only way forward appears to be just removing the alias
altogether.
(cherry picked from commit b4133ebc17)
The previous tentative to the fix got the order mixed up a bit. This
new fix has been re-verified to get them in the good order as per the
instructions in the following chapters.
The tests in <nixos/tests/installer.nix> are using `parted`, so they are
bound to be better tested than `fdisk`.
This is brought on by a couple issues, plus reports on IRC that the
`fdisk` instructions didn't work as expected.
* #39354
* #46309
* #39942
* #45478
Care was taken so that the other documented steps did not need changes.
In all this kerfufle, a slight re-organization of the Chapter has been
made, allowing better deep linking.
While it seemingly brings more attention to the macOS notes with the
default docbook template, it better represents which parts of the
section are about macOS, and which parts are simply in the flow of the
text; otherwise the last paragraph may be lost into the details for
macOS.
Nix commands inside the container have been broken since 18.03,
and no fix is yet in sight. Lets remove from the documentation
that this is a usecase that we support, as it doesn't seem
likely that this will be fixed before 18.09 either.
See #40355
- New dependency on 'getconf' binary for
3aa619e9ef/src/vm_memory_monitor.erl (L448)
- New dependency on 'socat' for systemd notifications
4a3ee3a336/src/rabbit.erl (L361)
- elixir_1_6 for a new 'rabbitmqctl' tool
- Replace patching with providing custom PATH, as we already have some
other things here
- Renamed package in all-packages.nix from a legacy spelling
Because when I see "config.system.build.manual.manual" after I forgot
what it means I ask "Why do I need that second `.manual` there again?".
Doesn't happen with `config.system.build.manual.manualHTML`.
This is taken from the 18.09 change, which was reverted on release-18.09
but not master. The now-false 18.09 release notes were just removed from
master in 29854e2426, but since the
underlying change is still there, release notes for 19.03 are warranted.
This commit takes the now-reverted release notes and reuses them for
that.
Fixed minor issue where kube-addon manager complaints about
/opt/namespace.yaml missing.
Added release notes with reference to Kubernetes 1.11 release notes.
closes#43882
This adds a release notes entry to make users (and especially
developers) aware so they no longer need to use </para><para> in option
descriptions as this is now done automatically on every two consecutive
newlines.
More details can be found in the commit message of f865d0feab.

What annoyed me for a long time was the fact, that in order to break
into a new paragraph, you need to insert </para><para> in the
description attribute of an option.
Now we will automatically create <para/> elements for every block that
is separated by two consecutive newlines.
I first tried to do this within options-to-docbook.xsl, but it turns
out[1] that this isn't directly possible with XSLT 1.0, so I added
another XSLT file that postprocesses the option descriptions that are
now enclosed in <nixos:option-description/> by options-to-docbook.xsl.
The splitting itself is a bit more involved, because we can't simply
split on every \n\n because we'd also split text nodes of elements, for
example:
<screen><![CDATA[
one line
another one
]]></screen>
This would create one <para/> element for "one line" and another for
"another line", which we obviously don't want because <screen/> is used
to display verbatim contents of what a user is seeing on the screen.
So what we do instead is splitting *only* the top-level text nodes
within the outermost <para/> and leave all elements as-is. If there are
more than one <para/> elements at the top-level, we simply don't process
it at all, because the description then already contains </para><para>.
