The collectd service runs as an unprivileged user by default, so it does
not leak more information to its data directory than any user can obtain
elsewhere by other means.
If people are running it as root and are worried about information leak,
we can add collectd group and set perms to 750.

Fixes#21198.
A secret can be stored in a file. It is written at runtime in the
configuration file.
Note it is also possible to write them in the nix store for dev
purposes.
This commit introduces a nixos module for the Openstack Keystone
service. It also provides a optional bootstrap step that creates some
basic initial resources (tenants, endpoints,...).
The provided test starts Keystone by enabling bootstrapping and checks
if user creation works well.
This commit is based on initial works made by domenkozar.
Split packages in three categories, all of them going into the system
package list:
- pre-requisite packages
- core packages
- optional packages
Add a new configuration option 'environment.lxqt.excludePackages' to
specify optional LXQt packages that should be excluded from system
packages.
Add 'gvfs' as a pre-requisite package, needed by 'pcmanfm-qt' to
handle virtual places, like "Computer" and "Network".
The boot tests import test-instrumentation.nix directly to create a VM
image that only contains things such as the backdoor and serial console
the same way as used by other NixOS VM tests.
With one difference though: It doesn't need nor want to have 9p
filesystems mounted, because we actually want to test an image rather
than re-using most stuff from the host's store.
Change tested against the boot.uefiUsb and ipv6 tests, just that it
becomes clear we don't break either the tests with 9p nor the boot
tests (which were already broken but now succeed).

even if cups rewrites its config file due to config changes made through
its web-based management UI, we need to keep the PATH pointing to
currently-live nix store directories. fixes#20806.
tune2fs marks the filesystem as clean to prevent resize2fs from
complaining.
But we were invoking it before we mounted the filesystem, so the
counters would increase to 1 and it broke the functionality.
By moving the call after the mount, I have confirmed it works by:
$ nix-build nixos/tests/ec2.nix

`systemd.hideProcessInformation = true`, would break interactions
requiring polkit arbitration such as initating poweroff/reboot as a
normal user; the polkit daemon cannot be expected to make decisions
about processes that don't exist as far as it is concerned.
systemd-logind lacks the `sys_ptrace` capability and so needs to be part
of the designated proc gid, even though it runs as root.

Fairly severe, but can be disabled at bootup via
grsec_sysfs_restrict=0. For the NixOS module we ensure that it is
disabled, for systemd compatibility.
- As noted on github, GDM needs different parameters for X.
- Making xserverArgs a true list instead of concat-string helps to
filter it and it feels more correct anyway.
- Tested: gdm+gnome, lightdm+gnome. There seems to be no logout option
in gnome, and gdm doesn't offer other sessions, but maybe these are normal.
It was deprecated and removed from all modules in the tree by #18319.
The wireguard module PR (#17933) was still in the review at the time and
the deprecated usage managed to slip inside.
$getter can be used once ipfs supports private/local networks
and or internet gets routed to the VMs

Previously, we would only set a default value, on the theory that
`boot.kernelPackages` could be used to sanely configure a custom grsec
kernel. Regrettably, this is not the case and users who expect e.g.,
`boot.kernelPackages = pkgs.linuxPackages_latest` to work will end up
with a non-grsec kernel (this problem has come up twice on the bug
tracker recently).
With this patch, `security.grsecurity.enable = true` implies
`boot.kernelPackages = linuxPackages_grsec_nixos` and any customization
must be done via package override or by eschewing the module.
Fixes#20713, though I'm certain nixpkgs contains loads of places
without proper quoting, as (ba)sh unfortunately encourages that.
The only plus side is that most of such problems in nixpkgs aren't
actually security problems but mere annoyance to those who are foolish
enough to use "weird" characters in critical names.
Allows one or more directories to be mounted as a read-only file system.
This makes it convenient to run volatile containers that do not retain
application state.
