What is the best way to build a Linux
distribution for an embedded system in a reproducible way,
caring about long term maintenance and small footprint?
PTXdist is a GPL licensed build system for
userlands, started by Pengutronix. It uses the Kconfig
configuration system from the Linux kernel.
Although PTXdist (without patches) still fits
on one disc, a whole root filesystem can be built as easy as
PTXdist is no distribution: our experience is
that binary distributions are too inflexible for embedded systems.
That's why PTXdist builds the target system directly from the original
sources. PTXdist is considered to be "executable documentation", which
means that the steps necessary to build a target system are put into
scripts which can be easily reviewed, but also executed with one click
by a less experienced user.
The current release of PTXdist is 2015.08.0

The development of PTXdist is performed on the GIT
server. Here you can checkout the current revision.
Patch System: Often the original
sources have to be modified to be able to cross compile them.
PTXdist has a patch repository, storing the necessary patches
until they are integrated upstream.
