v1.0.1

Bugfix Release

Fixed

• False positive reboot alert on Debian/Ubuntu hosts (rpm-kernel-mismatch)
  • Detection method 4 (RPM kernel comparison) was triggering on Debian-based systems where rpm is installed but not the primary package manager.
  • rpm -q kernel --last returns "package kernel is not installed" on Debian, causing awk '{print $1}' to extract "package" — which never matches uname -r.
  • Fix: Method 4 is now skipped on any system where dpkg is present.
