+# Configuration Management
+
+A significant improvement over the status quo of router configuration
+management interfaces is one of the most important design challanges for the
+rooter software stack.
+
+The problem could be split between "configuration management tools" (which
+would present a unified low-level interface to system and application
+configuration) and any "configuration interface" (which could be a web/http UI,
+command line apps, remote APIs, whatever) built on top of those tools.
+
+### Needs
+
+The scope of configuration includes routing and firewall policy, package
+versioning, web applications, mesh or tunneling configuration, radio channels
+and power, authentication and accounts, and more.
+
+Technical goals:
+
+* as complete as possible (twiddling all knobs through the same interface)
+* version controlled and transferable
+* low hassle for new software packages (aka, minimal "porting" effort)
+* UI agnostic libraries
+
+Usability goals:
+
+* auto-updatable without overwriting local customizations
+* ability to report the impacts of changesets before commiting
+* able to revert any individual change, and take named/dated snapshots/profiles
+* easy to share and apply configuration "patches"
+
+### Open Questions
+
+* how are type checking and exception recovery handled?
+* should applications have access to system configuration?
+* have fine grained access control or all root/admin powers?
+* provide "expert system" advice and warnings?
+
+### OpenWrt's UCI and LuCI
+
+OpenWrt's approach to configuration management is the Unified Configuration
+Interface (UCI); the LuCI web interface programatically generates configuration
+forms based on UCI definitions. It's written in Lua.
+
+UCI defines it's own standard configuration file format and stores
+configurations for each service in /etc/config/ (these can be edited from the
+command line). It then wisely (catching many corner cases) and efficiently
+(only restarting the services that need to be restarted) implements any
+differences between the configuration files and the running state of the
+system.
+
+Any additional services (in OpenWrt's ipkg package repository) need to
+implement UCI/LuCI compatability on their own, sometimes with a seperate
+*-luci helper package.
+
+### Augeas, Config::Model, Blueprint
+
+[Augeas](http://augeas.net/index.html) is a C library and collection of
+"lenses" which allow the manipulation of many types of configuration files
+through a standard treee/heirarchy interface. It is careful about not
+overwriting locally edited changes or even whiping out comments. It does not do
+any type checking of files.
+
+[Config::Model](https://github.com/dod38fr/config-model/wiki) is a perl project
+that both replicates a lot of the functionality of Augeas and can be run on top
+of Augeas. It seems to be debian specific, unclear how far along implementation
+is.
+
+[Blueprint](http://devstructure.github.com/blueprint/) is a system to "reverse
+engineer" configuration changes on Linux (UNIX?) systems. It is written in
+python and makes use of git for a storage backend. It includes tools for
+generating, version controlling, diffing, sharing, etc. It captures dpkg and
+rpm package information, locally edited configuration files, upstart/init.d
+configuration, and even source-installed software in /usr/local. It is not
+particularly fast out-of-the-box (might be possible to speed up), and is not
+oriented towards making small changes and having them applied immediately.
+
+I think that a good set of tools for rooter would be to use Augeas
+for micro-scale tasks (like configuration files "in real time") and Blueprint
+for macro-scale tasks (like snapshotting, sharing "patches", and version
+controlling defaults). Also needed is a layer on top of Augeas to manage higher
+level logic and service restarts; Config::Model might fill that role, or
+perhaps components of UCI could be extracted.
+
+### Bonus Features and Ideas
+
+Could host a (centralized?) configuration sharing and upvoting site where
+anybody could post snazzy configuration patchsets. Searchable by tags?
+Mark/vote as insecure or problematic? Comment/discuss/improve?

+# Big Picture
+
+*(circa Q1 2012)*
+
+The generic term "System on a Chip" refers to the fact that the CPU and many
+"peripherals" (USB, ethernet, memory controller, GPU) are integraded into a
+single package instead of being distributed across a motherboard via a
+northbridge and southbridge. There still needs to be external analog and
+digital circuitry for most "connectivity" interfaces like USB or ethernet to
+provide level conversion, isolation, etc. Notably, RAM is not usually
+integraded into the chip, and the large parallel bus to the RAM chips must be
+routed very carefully. Some newer chips (popular circa 2010?) include "package
+on package" technology where the RAM chip is right on top of the SoC to make
+routing easier (eg, iPhones, RaspberryPI).
+
+The establishment players for mobile ARM SoCs are TI (OMAP), Qualcomm
+([Snapdragon](http://en.wikipedia.org/wiki/Snapdragon_(System_on_Chip))), not
+regular ARM), Samsung ([Exynos](http://en.wikipedia.org/wiki/Exynos))), Marvell
+(Armada, Armada XP, )
+
+The establishment players for MIPS SoCs are Broadcom and Marvell (Kirkwood).

+Most likely rooter will run a variant/flavor of debian linux, with significant
+improvements and new software pushed upstream.
+
+### Linux Firmware Distributions
+
+These Linux-based distributions are all designed to run on very light-weight
+hardware. They use special filesystems optimized for mostly reads from a static
+archive with a few small writes to persist configuration information.
+
+* [OpenWrt](http://openwrt.org): Most popular and best maintained community
+ project. Has an entire packaging system for add-ons. Very wide hardware
+ support.
+* [DD-WRT](http://www.dd-wrt.com/site/index): non-libre, not recommended
+* [Tomato](https://en.wikipedia.org/wiki/Tomato_(firmware)): elegant, well
+ selected feature set, pleasant UI. Vanilla version has had little recent
+ development or porting, many forked variants.
+
+### BSD Firewall Distributions
+
+There are a series of "network appliance" firewall distributions oriented at
+business and enterprise networks. They usually run on dedicated hardware more
+powerful than commodity home routers, scaling up to multi-unit high performance
+rack mounted machines:
+
+* [pfSense](http://www.pfsense.org/): FreeBSD, forked from m0n0wall
+* [m0n0wall](http://m0n0.ch/wall/): FreeBSD, php interface
+* [Smoothwall](): commercial with "free" version
+* [zrouter](http://zrouter.org) freebsd router
+
+It's also worth noting that Juniper Network's junos router operating system is
+based on FreeBSD. Juniper equipment isn't as widespread as Cisco's iOS-based
+(not to be confused with the Apple operating system) routers, but is used for
+many of the most crucial 40Gbps+ routers at submarine fiber shore stations.
+
+### Debian/OpenWrt Hybrids
+
+A lot of people have thought about mixing the kernel, drivers, and
+configuration system from OpenWrt with the mainstream packages from Debian.
+
+* [DebianWRT](http://wiki.debian.org/DebianWRT)
+* [debwrt](http://www.debwrt.net/) is a stale project to bring debian packages
+ to the OpenWRT kernel/init system.
+
+### Genode
+
+Interesting nested resource-deterministic operating system "framework"; sort of
+like a generalization of a hypervisor. Strong ideas for minimizing the
+potential for security bugs and non-recoverable crashes. Might be appropriate
+for ensuring that "essential" network services keep running even if higher
+level apps crash or are compromised.
+
+[More thoughts
+here](http://mailman.rooter.is/pipermail/talk/2012-June/000023.html).

+-----------------
+Add 'init=/bin/bash' to boot args in u-boot. This can be accomplished on a

+External attackers likely could/would port scan and be able to identify the

+plan9 security: [Factotum](http://doc.cat-v.org/plan_9/4th_edition/papers/auth)
+
+Users should probably have a single "root" GPG key for every distinct
+identity/persona that they present to the external world, and then generate
+subkeys for use with each host/device and external service. This allows more
+fine grained control over revokation and access control (eg, if a device is
+lost then suspend/revoke that key). An API or tools to help distribute
+certificates, signing information, and revokations would be helpful.
