How does this handle kernel files that have more than the version in their file? something like initramfs-6.4.2-sched-ext vs initramfs-6.4.1

How does this handle kernel files that have more than the version in their file? something like initramfs-6.4.2-sched-ext vs initramfs-6.4.1

For this purpose, I created a script to test the functionality:

package main

import (
	"fmt"

	"github.com/hashicorp/go-version"
)

func getLatestKernelVersion(files []string) string {
	var maxVer *version.Version
	for _, file := range files {
		verStr := file[8:]
		ver, err := version.NewVersion(verStr)
		if err != nil {
			fmt.Println("Error parsing version:", verStr, "Error:", err)
			continue
		}
		if maxVer == nil || ver.GreaterThan(maxVer) {
			maxVer = ver
		}
	}
	if maxVer != nil {
		return maxVer.String()
	}
	return "no valid kernel version found"
}

func main() {
	files := []string{
		"vmlinuz-6.4.1",
		"vmlinuz-6.4.2-sched-ext",
		"vmlinuz-6.3.1-debug",
	}

	fmt.Println("Latest Kernel Version:", getLatestKernelVersion(files))
}

here is the result: Latest Kernel Version: 6.4.2-sched-ext
