The article unfortunately does a horrendous job at highlighting AerynOS' unique features by only giving vague descriptions without going into any technicality that matters.

FWIW, my two cents on AerynOS:

• It offers (yet) a(nother) novel approach to atomic distros. The gist for its ambition (or, at least, my understanding of it) would be NixOS, but with FHS intact and without a DSL.
