This is a small utility which shows the installed and running Linux kernel on ArchLinux. It is useful if one didn't notice that the kernel got updated and suddenly your USB drive won't mount because the needed kernel module can't get loaded.
To get the version of the installed kernel it uses pacman -Q linux and to get
the version of the running kernel it uses uname -r.
