opkg is a lightweight package manager used primarily on OpenWrt and other embedded Linux systems. It provides functionality similar to apt or yum but with minimal resource requirements suitable for routers and IoT devices.
The package manager handles dependencies, downloads packages from configured repositories, and manages the installation database. Configuration is stored in /etc/opkg.conf and repository lists in **/etc/opkg/*.conf**.
Space is often limited on embedded devices, so opkg supports installing packages to external storage and manages package state efficiently.

Package lists must be updated (opkg update) before installing new packages. Storage space on embedded devices is limited; check available space before installing. Some packages require rebooting the device to take effect. Dependencies may require manual resolution on resource-constrained systems.
