Open Wrt is configured using a command-line interface (ash shell), or a web interface (Lu CI).
There are about 3500 optional software packages available for installation via the opkg package management system.
This will preserve things like Open Wrt network settings, Wi Fi settings, the device hostname, and so on.
The first part of the upgrade process is to prepare for the upgrade.
Open Wrt can run on various types of devices, including CPE routers, residential gateways, smartphones, pocket computers (e.g. It is also possible to run Open Wrt on personal computers, which are most commonly based on the x86 architecture.
which in turn enabled independent developers to create additional derivative versions.
This document is written for debian like operating systems, if you use any other system you will have to install the equivalent packages for your distribution.
Note that building Open WRT requires at least 5 gigabytes of hard disk space and about two hours on a modest machine.
All components have been optimized for size, to be small enough for fitting into the limited storage and memory available in home routers.Any configuration files or data files placed in locations not specifically listed as being preserved below will also be lost in an Open Wrt upgrade.The Open Wrt build system configuration interface handles the selection of the target platform, packages to be compiled, packages to be included in the firmware file, some kernel options, etc. I'm assuming this is because the default repo's are static and don't get updated.So, finally, the question: Are updates available for Open WRT, without needing to reflash the whole machine to the latest/greatest (beta? Added to this, the Open Wrt developers are themselves only maintaining a smaller set of packages – which includes all default packages – but, the feeds-script makes it very simple to handle a locally maintained set of packages and integrate them in the build-process.
