Twenty years of my work with Arm architecture
I spent three years working on OpenZaurus distribution. In my free time. Started as a user, went through being developer and ended as a release manager. Through those years I moved from my SL-5500 to the c760 (donated by user). Had several other Zaurus models on my desk in meantime.
Those were interesting years. I learnt a lot about structure of Linux filesystem, how packaging works, all those differences between build-time and install-time dependencies, sorting out upgrades etc. And how to cooperate with other developers and users. Also how to avoid those who deserve to be ignored.
