## Summary
The `linux-tools` package is no longer available in the VyOS repository. This is an unexpected and unpleasant change, as the package is essential for proper kernel debugging.
## Expected Behavior
The `linux-tools` package should be present in the repository to allow users to perform kernel-related debugging and performance analysis.
## Observed Behavior
The package is missing from the repository, making it impossible to use tools like `perf` and other debugging utilities.
## Impact
- Kernel debugging is significantly hindered.
- Performance analysis and tracing tools provided by `linux-tools` are unavailable.
## Suggested Fix
Reintroduce the `linux-tools` package to the repository.
