These days people can laugh at the UNIX concept of connecting typewriters but in the lexicon of the 60's the typewriter was the person and the typwriting machine was the compositing device. Gotta love hacker humor tho. 

Unix is dead and all thats left is Linux and some rounding errors. & Ask grampa about getty.

Having struggled somewhat with upgrading to systemd targets myself, his introduction of a concept of a system layer abstraction which is used for linking between kernel and user space in that dynamically described timing space is fascinating. In my opinion so far, systemd is not particularly a dll hell nor is it a static heaven. Maybe "compurgatory" is the term for this stage of change. Purgatory is about learning to change prior to enlightenment and absent a culture of contempt.
