varcacheopkgconf

Varcacheopkgconf is not a standard term in mainstream Linux distributions. In practice, it appears as a concatenated token used in some build scripts or documentation to denote a path or variable related to the opkg configuration cache. The name combines common filesystem and tool elements: var (the /var filesystem), cache (cache storage), opkg (the lightweight package manager), and conf (configuration). Because it is not standardized, its exact meaning depends on the project that uses it.

Opkg is a lightweight package manager commonly used in embedded systems. Its configuration is typically held in files such as /etc/opkg.conf, with feed lists and caches stored under directories like /var/cache/opkg and /var/lib/opkg/lists. In some scripts, a variable named VARCACHEOPKGCONF may be defined to point to a cached or prepared opkg configuration used during image building or chroot operations in embedded environments.

Usage in scripts is often to reference the variable as a path to the opkg configuration, for example setting VARCACHEOPKGCONF=/var/cache/opkg/opkg.conf or exporting it for subsequent commands. The variable can then influence where opkg reads its configuration, or where it stores cache and list data during a build or deployment step.

Notes and cautions: Because VARCACHEOPKGCONF is not standardized, its actual value and location can vary between projects. When encountered, review the specific project’s build system or documentation to determine the intended path, permissions, and how it interacts with opkg operations in that environment.
