Puritan
Source code. README. Latest version: 0.4.
Puritan is a disk-image compiler which converts source material including packages, activities, and hacks into installable disk images. It consists of two pieces: a UI and a family of compilations (example). The compilations are simple Python programs which populate a filesystem with the materials you supply, then wrap it up with a bow-tie. The UI runs the compilations in a controlled environment created by Mock and configured according to the compilation's bootstrap and dependencies files. Puritan's only installation dependencies are
git-core python-2.5 mock
On Fedora
The Puritan UI is invoked by installing a puritan rpm (built from the ui branch)
wget -O puritan.rpm http://dev.laptop.org/~mstone/releases/RPMS/puritan-0.4-1.olpc2.noarch.rpm sudo rpm -Uvh puritan.rpm
then by checking out a 'puritan compilation' to be run by /usr/bin/puritan
$(git clone git://dev.laptop.org/users/mstone/puritan compilation; cd compilation; git checkout origin/devel_jffs2) puritan -v ./compilation HEAD ./results build
If you want to download a set of RPMs for post-processing (for example, because you want to layer a risky feature on top of them), you can also run
puritan -v ./compilation HEAD ./results download
Your results should appear in ./results.
On Debian
Note: yum seems to be broken on Debian at the moment, which is preventing this recipe from working. :( --Michael Stone 03:02, 7 March 2008 (EST)
sudo apt-get install mock git-core sudo usermod -a -G mock $USERNAME git clone git://dev.laptop.org/users/mstone/puritan ui $(git clone git://dev.laptop.org/users/mstone/puritan compilation; cd compilation; git checkout origin/devel_jffs2) /usr/bin/python2.5 ui/puritan/main.py ./compilation HEAD ./results
Help Out
Finally, please help improve puritan by
- making puritan work on your platform
- maintaining the devel_ext3 compilation
- adding some reasonable package or buildroot caching system so that it runs faster without impairing build repeatability
- improving the UI with commands for manipulating compilations, or for diffing builds, or for profiling compilations, or ...
