What is Opkg?
Opkg is the package management system used on embedded Linux systems, most notably OpenWrt. It was designed to replace the Rpm Package Manager (RPM), Debain packages, Alien packages, and the Red Hat Package Manager (RPM), but it can be used with any Linux distribution. With opkg you can easily download and install software packages from the Internet to keep your router up to date without a lot of hassle.
What is Archlinux?
Arch Linux is a simple and lightweight Linux distribution, and was created with the KISS principle. A part of the base of Arch Linux is the pacman package manager, which then makes it easy to install and update applications and how they work with each other. The simplicity and open community is conducive to attracting developers as well as using the operating system on a day-to-day basis. Power users can make changes to how their systems works, both visually and technically.
