Summary

  • Add SIGSYS to the signal handler list in CrashCapture so seccomp violations produce a meaningful error message instead of generic "VM exited unexpectedly"
  • Add seccomp-specific troubleshooting hint in CrashReport when SIGSYS is detected

Test plan

  • Verify cargo check -p boxlite passes
  • Trigger a seccomp violation and confirm the error message mentions seccomp/SIGSYS

Add SIGSYS to the signal handler list so seccomp violations produce
a meaningful error message instead of generic "VM exited unexpectedly".
