I’ve mentioned it before, but the tool ‘synth‘ is what DragonFly uses to build all the dports binaries – over 30,000 packages, though I’m typing that from memory and not from looking at a tool. Anyway, the one part of the release process I’ve never touched was the package building – and now it’s documented. This document is oriented towards DragonFly releases – but if you wanted to create your own package repo with custom options, this is the way to do it.
A running description of activity related to DragonFly BSD.
As a cautionary tale, building with synth can destroy your pkgng database and leave you with a system that has both a broken synth and pkgng setup. It’s a good tool, but be sure to backup and to read before using it.
