Purge contents of `workDir` as root to also allow the removal of files
marked as read-only. It is easy to create read-only files in `workDir`,
e.g., by copying files from the Nix store.
This builds on top of nixpkgs mainline 00d8347180
with the following two PRs cherry-picked:
- https://github.com/NixOS/nixpkgs/pull/192670
- https://github.com/NixOS/nixpkgs/pull/192668
using the following command:
```
nix build -f nixos -L \
-I nixos-config=nixos/modules/installer/sd-card/sd-image-powerpc64le.nix \
config.system.build.sdImage
```
I was able to successfully boot the image, although it boots to a login prompt
rather than a shell, and won't accept the empty password for `root`. I guess
I'll have to figure out why that is.
To boot the image: `zstd`-decompress the it, mount it, and use `kexec`:
```
cd boot/nixos
kexec -l \
*-vmlinux \
--initrd *-initrd \
--dt-no-old-root \
--command-line="$(grep APPEND ../extlinux/extlinux.conf | sed 's_^ *APPEND *__')"
```
The machine I used for testing has only one storage device which is completely
allocated to LVM. It appears that the NixOS ISO loader doesn't look for
partition tables within LVM volumes. To work aroundn this, I had to extract the
`ext4` image within the partition table within the `sd-card` image and put that
in its own LVM volume. This likely won't be an obstacle for users who write the
image to a USB stick or similar.
GDM and LightDM are already using this approach. It also allows us to
enable Kwallet integration more globally without generating stray PAM
services.
The default configuration of login service includes both options sddm
was setting explicitly.
This removes two unused service configs from /etc/pam.d/ and, more
importantly, reduces confusion.
* kdm no longer exists in nixpkgs
* `pam.d/gdm` is not used by gdm
* `pam.d/lightdm` IS used by lightdm but hardcoded using .text rather
than attrset+template.
Provide a module to configure Coqui TTS, available as `tts` in nixpkgs
for a few releases already.
The module supports multiple servers in parallel, so multiple languages
and testing scenarios can be covered, without affecting any production
usage.
Injecting configuration specific dependencies into the
propagatedBuildInputs of the home-assistant package forces alot of
rebuilds while setting up home-assistant, which is annoying.
By passing optional dependencies into home-assistant via the systemd
units PYTHONPATH environment variable, only he concatenation of
library paths in the systemd unit requires a rebuild.
This also means users can rely heavily on the cached home-assistant
package and will rarely have to build from source, if ever.
Since 1.2.0, kanata handles missing keyboards well:
- only one keyboard need to be present when kanata starts;
- if linux-continue-if-no-devs-found is set to yes, all keyboards can
be missing at the beginning;
- all keyboards can be (un)pluged when kanata is running.
For simplicity, linux-continue-if-no-devs-found is set to yes and
systemd patch activation is removed.
using readFile instead of fileContents (or using indented strings) can
leave a trailing newline that causes build errors in systemd units and
has previously caused runtime errors in wireguard scripts. use
singleLineStr to strip a trailing newline if it exists, and to fail if
more than one is present.
...but still allow for setting `dataDir` to a custom path. This gets
rid of the use of the deprecated option PermissionsStartOnly. Also, add
the ability to customize user and group, since that could be useful
with a custom `dataDir`.
trying to get all of the podman functionality to work with the wrapper
is becoming more complicated with each release, it isn't sustainable
removing the wrapper does mean that using extraPackages will need to build from source
- include pkgs.zfs by default in the wrapped podman used by the module so it is cached
- anyone using zfsUnstable will need to build from source
- remove unnecessary serviceConfig overrides
- set HELPER_BINARIES_DIR during build
- use install.bin target on linux for podman/tmpfiles
- also installs quadlet/rootlessport in libexec
- remove unnecessary rootlessport output
- remove unnecessary substituteInPlace
