In order for DynamicUser = true to work in services, we need the
nss-systemd module to be able to resolve the user and group names
generated dynamically.
Evaluation error introduced in a0d464033c.
If the value for timeZone is null it shouldn't be even tried to coerce
it into a string.

Creating and then erasing the key relies on the disk erasing data
correctly, and otherwise allows attackers to simply decrypt swap just
using "secretkey". We don't actually need a LUKS header, so we can save
ourselves some pointless disk writes and identifiability.
In addition, I wouldn't have made the awful mistake of backing up my swap partition's LUKS header instead of my zpool's. May my data rest in peace.
While systemd suggests using the pre-defined graphical-session user
target, I found that this interface is difficult to use. Additionally,
no other major distribution, even in their unstable versions, currently
use this mechanism.
The window or desktop manager is supposed to run in a systemd user service
which activates graphical-session.target and the user services that are
binding to this target. The issue is that we can't elegantly pass the
xsession environment to the window manager session, in particular
whereas the PassEnvironment option does work for DISPLAY, it for some
mysterious reason won't for PATH.
This commit implements a new graphical user target that works just like
default.target. Services which should be run in a graphical session just
need to declare wantedBy graphical.target. The graphical target will be
activated in the xsession before executing the window or display manager.
Fixes#17858.
gyre-fonts provides high-quality TrueType substitutes for standard PostScript
fonts. Unlike most other distributions, NixOS does not install Ghostscript and
its Type 1 fonts by default, so we must get the standard fonts elsewhere.
When a user or group is revived, this allows it to be allocated the
UID/GID it had before.
A consequence is that UIDs and GIDs are no longer reused.
Fixes#24010.
The inability to run strace or gdb is the kind of
developer-unfriendliness that we're used to from OS X, let's not do it
on NixOS.
This restriction can be re-enabled by setting
boot.kernel.sysctl."kernel.yama.ptrace_scope" = 1;
It might be nice to have a NixOS module for enabling hardened defaults.
Xref #14392.
Thanks @abbradar.
