-[[!meta title="Opkg in ProteanOS"]]
-ProteanOS uses [opkg][opkg] to manage packages after installation with
-[[prokit|dev/prokit]]. opkg has a long history through different umbrella
-projects and maintainers. After [more than three years since the 0.1.8
-release][pbarker-maint], regular releases were resumed in August/September 2013
-with the [0.2.x series][0.2.x-NEWS]. [Starting in December 2013][yocto-move],
-development of opkg was moved from Google Code to infrastructure of the Yocto
-Project, a project of the Linux Foundation that also serves as a home for
-BitBake, OpenEmbedded, and Poky.
-The Growing Lightweight Package Management System
-Development has continued in the 0.3.x series. Multiple maintainers and
-contributors have added various bugfixes, new features, and architectural
-improvements to make opkg a more modern and maintainable codebase.
-For a long time, opkg had an embedded copy of BusyBox's libbb for reading
-archives (as packages supported by opkg are doubly nested archive files). This
-copy of libbb had grown
-[[stale_and_heavily_patched|dev/todo/removing-libbb-from-opkg]]. Finally, [in
-2013/2014][drop-libbb-git], libbb was [replaced][add-libarchive] with
-[libarchive][libarchive]. This removed a large amount of old code from opkg,
-however it added a dependency on a large library that was never designed with
-the code size restraints of embedded systems in mind.
-And in August 2015, support for external dependency solver libraries was added,
-so as to remove additional complexity from opkg and leave dependency solving to
-another project. Unfortunately, this also [pulls][solver] in
-[another][solver-patch] large [library][oe-pw-libsolv], openSUSE's
-[libsolv][libsolv]. As of now, this dependency is still optional, and the
-original internal solver can still be used. However, the current maintainer has
-[indicated][libsolv-focus] that the internal solver will eventually be
-The Future of the Past
-ProteanOS currently [still uses][pro-opkg-cl] the [0.2.x series][0.2.x]. The
-increasing size of modern opkg (starting with the 0.3.x series) and its
-dependencies makes it increasingly unsuitable for small system distributions
-like ProteanOS. We will need to find a solution going forward.
-[OpenWrt][owrt] and [libreCMC][lcmc] use a [0.1.8+r618][opkg-owrt-lcmc] version
-(SVN revision 618, between 0.1.8 and 0.2.0) with [numerous local
-patches][owrt-patches]. LEDE [switched][lede-switch] their [opkg
-package][lede-pkgdata] to [their own fork][lede-fork], which is based on the
-same 0.1.8+r618 version that OpenWrt and libreCMC use.
-LEDE actively maintains their opkg fork and backports changes from upstream.
-This may be the best and easiest option for ProteanOS, although there are a
-couple of minor problems:
- 1. It still has [libbb][lede-opkg-libbb], and
- 2. It pulls in a new, but small, dependency: LEDE's [libubox][lede-libubox].
-Note also that the original Autoconf/Automake-based build system was
-[removed][lede-opkg-at] and [replaced][lede-opkg-cm] with CMake.
