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 format it for distribution. The UI runs the compilations in a controlled environment created by Mock and configured according to the compilation's bootstrap and dependencies files.

Fedora Instructions

NB: These instructions refer to out-of-date code; for the newest code, check out the 'ui', '767', and 'dev' branches of puritan (anon. clone)

The Puritan UI is invoked by yum-installing puritan, 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     # read help
 sudo puritan -v ./compilation HEAD ./results build

Some puritan compilations now feature both 'download' operations:

 sudo puritan -v ./compilation HEAD ./results download

and 'interactive' error-handling:

 sudo puritan -v ./compilation HEAD ./results build -- -i

Debian Instructions

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 - it's only dependencies are python2.5, git-core, and mock!
• 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 ...
