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.
It can also detect if critical packages like systemd got updated which may also make a reboot necessary.
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
Alternatively one can install it with cargo:
cargo install reboot-arch-btw
This project requires Rust 1.65.0 or newer. Also you need to have dbus installed.

It will also show a desktop notification indicating that you probably want to reboot your system.
One can use --reboot-packages or --reboot-packages to set the list of
packages which should also trigger a notification if they are updated.
``` $ reboot-arch-btw --help Check the currently installed kernel against the currently running one.
