I tried Alpine once and it was amazing how fast it was. Many package installations were almost instantaneous. I remember checking after installation if the package was installed, because I didn't believe it, that fast it was. I would like to hijack this thread and ask: how does Alpine's package build system works? I use Void's, because package builds are thinly isolated thanks to user namespaces. This makes sure, that the configure scripts are only detecting what you want. Also, what is important for me, you can mostly do everything without root privileges. I use it to generate images of my own Linux distribution and easy hacking around it is also a big plus for me.
