Say I am interested in only a single ROOT set a of features. This could be IO, Fits etc. Is it possible to install just the features I want without having to install the entire ecosystem?
Since you contacted also privately ROOT Core Developers about this matter, I’d like to elaborate a bit on the Minimal option for the benefit of the entire ROOT Community.
It is indeed the right option to build the minimal ROOT: we’ll document more in detail what components it provides on the website soon.
