Additional Features
Notifications: Users (including myself) do not actively monitor their journald logs, so a userland notification daemon has been included to monitor journald logs and display them to the user using libnotify. Notifications are enabled after install by XDG autorun, so if your DM does not have /etc/xdg/autostart it will fail.
DKMS: Dynamic Kernel Module Support has been added for Arch and Fedora/CentOS (looking to expand in the near future). DKMS allows the (near) seamless upgrading of Kernel modules during kernel upgrades. This is mainly important for distributions that provide rolling releases or upgrade their kernel frequently.

Kernel Module Arguments
The kernel module can be passed a specific timeout argument on insertion through the command line.
To do this, run the command sudo insmod tyton.ko timeout=X where X is the number of minutes you would like the kernel module to wait before executing its scan again.
AUR
Tyton is available on the AUR here.
You can install it using the AUR helper of your choice:
