* Previously, both the xorg and wayland backend were built into the yambar
package. The refactor breaks up each backends to its separate, with xorg
being the default. Thus yambar users on wayland should switch to the
yambar-wayland package.
For security reasons, and generally, it is best to create a more fine
grained group than plugdev. This way users that wish to tweak razer
devices don't have access to the entire plugdev group's permissions.
This is of course a breaking change.
The test certificate expiration date was set to the default 30 days.
This certificate is generated through its own derivation. As with
every derivation, it gets cached by cache.nixos.org once we build it.
In practice, we rebuild this derivation only if one of its input
changes. The only inputs here being openssl and stdenv.
While it's not an issue on the unstable branches, it can be
problematic on a stable release: the test will fail after 30 days.
Extending the certificate lifespan from 1 month to 100 years to prevent
it from getting expired while being cached.

for more context.
Nullmailer expects that this directory exists (see
073f4e9c5d/doc/nullmailer-send.8 (L185)).
When it doesn't and an email cannot be sent due to a permanent failure
or has been in the queue longer than queuelifetime (7 days), message
"Can't rename file: No such file or directory" starts appearing in the
log and nullmailer never sends "Could not send message" notification.
This means that the user may never learn that his email was not
delivered.
Previously the driver was configured exclusively through convoluted
environment variables.
Now the driver's defaults are configured through env variables.
Some additional concerns are in the github comments of this PR.
This fixes:

This option allows basic configuration of the compression technique
used in the backup script. Specifically it adds `none` and `zstd` as
new alternatives, keeping `gzip` as the default.
