# Objective
- Many of our CI workflows contain a `NIGHTLY_TOOLCHAIN` environmental
variable.
- This specifies which nightly to use. If there is a bug in one of the
nightlies, we can pin the toolchain to be an earlier version.
- Both the daily and weekly workflows do not use the nightly compiler,
but still have a `NIGHTLY_TOOLCHAIN` variable.
## Solution
- Delete the unused variable.
# Objective
- There are several occurrences where different actions install alsa,
udev, and various other libraries for Linux.
- This is repetitive and can be an issue if the dependencies required by
Bevy ever change.
## Solution
- Create a custom action for installing Linux dependencies.
- It can be used by adding `- uses:
./.github/actions/install-linux-deps`.
- It supports configuring which libraries are installed using the `with`
property.
- It does nothing if not run on Linux, so workflows don't need to worry
about adding `if: ${{ runner.os == 'linux' }}`.
## Discussion
- The only instance where this action is not used cleanly is for the
`run-examples-linux-vulkan` verification job. I need to investigate
further the flags and dependencies that it installs.
# Objective
Get an early warning if any new rust lints will break CI. Closes#12625
## Solution
Test the main branch against the Rust beta every week.
## Additional Possibilities
The action currently creates an issue if anything fails. The issue could
use a label like `C-Weekly` but somebody with the ability to create
issue labels would have to add it.
Another possibility would be to use discord webhooks. That would need
somebody with the access to create webhooks on discord and somebody with
the rights to connect that webhook to this repo,
