- The test was failing because it assumed the process `redis-server` was not already running.
- This commit adds a check to see if the process exists. If it does, it stops it before starting it.
- If it doesn't exist, it creates it before starting it.
- This ensures the test is more robust and reliable.
- Fix issues in package installation and removal across
different platforms (Ubuntu, macOS, Alpine, Arch).
- Improve error handling and add sudo support where
necessary.
- Enhance screen status check to accurately reflect
process activity.
- Address minor bugs in `db.v`, `done.v`, and
`net_test.v`.
- Correct minor inconsistencies in package names.
