Lo and behold, we're finally catching up with Mozillas very own firefox
build in terms of speed.
PGO is an optimization technique in which in a first step we create a
build that supports instrumentation, meaning we can use it to create a
profile of how the browser behaved during usage. Then in a second pass
we create the final build that uses the acquired profiling data to
optimize the browser for the workload it actually received during
profiling.
The downside is that with PGO we now need to build Firefox twice, which
increases the build time from around 20 minutes to roughly 50 minutes.
In the Speedometer 2.0 benchmark multiple tests could see a
responsiveness improvemeant around 20-25%, which makes the increased
build time well worth it.
Sadly this benefit seems limited to x86_64-linux, builds on
aarch64-linux get stuck during profiling and I haven't found out why.
Finally, after a long time, we can say:
Closes: #76484
Supersedes: #129503
Before this patch, services.dendrite.environmentFile is used for
secrets and environment variable substitution only happens when this
option is used.
systemd-247 provides a mechanism called LoadCredential for secrets and
it is better than environment file. See the section of Environment=
in the manual of systemd.exec for more information.
This patch always substitute environment variables, which enables the
usage of systemd LoadCredential.
* With the upgrade to waydroid to 1.2.0, dependencies that previously
were shipped in the service's path have been moved to the waydroid
package.
* Make sure /var/lib/misc exists when starting waydroid. As required

This patch allows creation of files like
/etc/systemd/system/user-.slice.d/limits.conf with
systemd.units."user-.slice.d/limits.conf" = {
text = ''
[Slice]
CPUAccounting=yes
CPUQuota=50%
'';
};
which previously threw an error
Also renames the systemd-unit-path test to sytsemd-misc, and extends it to
test that `systemd.units` can handle directories. In this case we make
sure that resource limits specified in user slices apply.
GNOME Shell 42 switched an icon for the accessibility menu in the top panel
to one from gnome-control-center instead of a legacy one from adwaita-icon-theme:
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/2155
Let’s add that dependency to the systemd unit since installing it
through `environment.systemPackages` is not enough due to environment isolation.
The tests complained:
/nix/store/nm3nf5y4hzgmy00lw5s6ls68j38y84y0-gjs-1.72.0-installedTests/libexec/installed-tests/gjs/scripts/testCommandLineModules.sh: line 90: gjs-console: command not found
But they still passed.
Sendto device selection is removed in gnome-bluetooth 42.
I decide it is not worth to maintain a legacy gnome-bluetooth
package for the contract.
This should also be broken in elementary OS 7.
Browser Integration requires setgid and setuid programs, which needs to be done in the system configuration.
This is cleaner than the ad-hoc ways we have to set things up for platforms without a global configuration file.
