Closing Notes
Solus is one of those unique distribution which has smaller user base but provides well tested rolling release system. With a different package manager eopkg, independent repository and other uniqueness, it is a well suited desktop based Linux for all use cases. I wish they get the mainstream popularity they deserve and provides a Xfce variant in the future.
