+[[!meta title="opkbootstrap"]]
+
+opkbootstrap is a tool to bootstrap the installation of a basic root filesystem
+in a specified target directory.  It will read package indices from a
+[[package_archive|dev/archive/layout]] to determine which packages must be
+installed, download the packages, unpack them into a target directory, and
+configure them for use.
+
+*opkbootstrap is a goal for [[release_1.0|dev/releases/1]].*
+
+*opkbootstrap is part of a project in the
+[[fall_2012_NJIT_CCS_Capstone|dev/capstone-2012f]].*
+
+
+Use Cases
+=========
+
+opkbootstrap will have two main types of uses.  The first is installation of
+operating systems for use on hardware devices.  opkbootstrap can be pointed to a
+package archive on a network or on local media (e.g. an installation CD).
+
+The other type of use is installation of development systems.  Distribution
+developers will be able to use opkbootstrap to set up isolated systems in which
+they can build their packages.  Additionally, opkbootstrap can be used to set up
+isolated systems managed by build daemon processes to automatically build
+packages.
+
+
+Portability Concerns
+====================
+
+opkbootstrap should be written to run on any operating system that at least
+mostly conforms to [POSIX.1-2008][posix.1-2008] XCU and has `tar` (or `pax`?)
+and `chroot` programs.
+
+opkbootstrap needs to perform the tasks of a package manager (resolving
+dependencies, unpacking packages, etc.) because opkg is not expected to be
+present on host systems.
+
+
+Status
+======
+
+[Development has begun][opkbootstrap-git] on opkbootstrap.  It currently
+downloads old ipkg-style source lists, finds essential packages, and unpacks
+packages.  To do are resolving dependencies, downloading packages, setting up an
+isolated environment ("chroot"), and running maintainer scripts.
+
+
+References
+==========
+
+debootstrap
+-----------
+
+opkbootstrap will be similar in function to [debootstrap][debootstrap]
+([repository][debootstrap-git]) of Debian and Debian-derived distributions.
+
+debootstrap is therefore a good reference for functionality and logic.
+
+ipkg
+----
+
+[ipkg][ipkg-wp] ([old Handhelds.org page][ipkg-hho]), "the itsy package
+management system", is the predecessor to opkg.  ipkg was originally written by
+Carl D. Worth in 2001 as a monolithic UNIX shell script, complete with "black
+magic" and "blacker magic" sed scripts.  The old ipkg script can still be found
+in some old repositories, such as [OpenWRT's][ipkg-openwrt] and
+[NSLU2's][ipkg-nslu2].
+
+ipkg may be a decent reference for package unpacking and configuration.
