# 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.
