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 libalpm (shipped with
pacman) to query the local pacman database. To get the version of the running
kernel it uses uname -r.
You may just install it from the AUR: * https://aur.archlinux.org/packages/reboot-arch-btw for the latest release * https://aur.archlinux.org/packages/reboot-arch-btw-git for the latest master
This project requires Rust 1.53.0 or newer. Also you need to have dbus installed.
