Also, add some sleep statements in between, which seems to at least feel
like it causes
> WARNING: Device /dev/vda* not initialized in udev database even after waiting 10000000 microseconds.
To occur less frequently.
This eventually still succeeds after some amount of waiting, I suspect
some racyness in the way lvm's udev-triggered scripts trigger other
units.
- use installTargets again ("install", and
"install_systemd_{generators,units,configuration}" when udev is not
null)
- The call to the blkid binary in lvm2's 13-dm-disk.rules file
disappeared (so we don't need to patch in blkid anymore).
lvm seems to rely on udev's internal blkid functionality.
- Call /run/current-system/systemd/bin/udevadm instead
of ${systemd}/bin/udevadm in the lvm activation generator.
This is not necessary to break the dependency cycle (as we don't use
that file when building without udev), but a good idea anyways -
We want to trigger the udevadm of the current system, not the one
that lvm was built with.
ITS rules are used for extracting translatable strings and they have
been moved to external files in 2.13.92 so they are not needed in
the config files themselves.
Removing them also cuts down on errors/warnings produced when using
older versions of fontconfig (< 2.12.92). Now it will only complain
about the description element but that is fortunately just a warning,
not errors like the ones caused by the its attributes.
Thanks to this, we can change the config version in NixOS module
back to 2.11 allowing us to re-use the 2.13/2.14 configs for apps
built against 2.12 fontconfig.
With previous patch, we no longer load non-versioned fonts.conf file to avoid incompatibilities
but this also means fontconfig will not load system-wide installed fonts on non-NixOS systems.
As a compromise, let's hardcode the FHS font paths to the built-in config so that the system
fonts work there. Unlike with the system config we do not need to worry about compatibility as
incompatible font files will be simply ignored.
Of course there will still be disparity if the system install fonts to some other location than
these two but I am afraid this is the best we can do.
See https://github.com/NixOS/nixpkgs/pull/73795#issuecomment-635771967 for discussion.
Falling back to unversioned `/etc/fonts/conf.d` when versioned one does not exist
is problematic since it only occurs on non-NixOS systems and those are likely
to have a different version of fontconfig. When those versions use incompatible
elements in the config, apps using fontconfig will crash.
Instead, we are now falling back to the in-package `fonts.conf` file that loads
both the versioned global `conf.d` directory and the in-package `conf.d` since using
upstream settings on non-NixOS is preferable to not being able to use apps there.
In fact, we would not even need to link `fonts.conf`, as the in-package `fonts.conf`
will be always used unless someone creates the global one manually (the option is still
retained if one wants to write a custom NixOS module and to avoid unnecessary stat call on NixOS).
Additionally, since the `fonts.conf` will always load `conf.d` from the package, we no longer
need to install them to sytem `/etc` in the module. This needed some mucking with `50-user.conf`
which disables configs in user directories (a good thing IMO, NixOS module will turn it back on)
but otherwise, it is cleaner. The files are still prioritized by their name, regardless of their location.
See https://github.com/NixOS/nixpkgs/pull/73795#issuecomment-634370125 for more information.
This permits using method_set_hostname but still denies
method_set_static_hostname. As a result DHCP clients can now always set
the transient hostname via the SetHostname method of the D-Bus interface
of systemd-hostnamed (org.freedesktop.hostname1.set-hostname).
If the NixOS option networking.hostName is set to an empty string (or
"localhost") the static hostname (kernel.hostname but NOT /etc/hostname)
will additionally be updated (this is intended).
From "man hostnamectl": The transient hostname is a fallback value
received from network configuration. If a static hostname is set, and is
valid (something other than localhost), then the transient hostname is
not used.
Fix#74847.
Note: It's possible to restrict access to the org.freedesktop.hostname1
interface using Polkit rules.
The generated yarnNix file doesn't need to be part of the mkDerivation.
And doing so prevents other platforms from reproducibly instantiating
it. With this change you can e.g. do
darwinPkgs.yarn2nix.mkYarnPackage {
# ...
yarnNix = pkgs.yarn2nix.mkYarnNix {
yarnLock = ./yarn.lock;
};
}
Which is a darwin derivation, but can still be instantiated reproducibly on Linux.
