I'm planning to move over to Guix over NixOS, as soon as my current situation improves and possibly import a new libre respecting laptop (Star Labs is thankfully available in India). I do have a very old laptop with a Celeron processor and 4GB of RAM with Guix installed already, and what has come to my attention is that it uses shepherd.
I'm not actually against or for systemd, in fact, I am not really sure why I should even care - maybe it is because I'm still not on to the level of a power user. Since I'm starting to learn kernel basics to prepare for GNU/Hurd contributions in the nearest possible future and shepherd seems to be what the GNU folks will be using, is there any reason why I should even care about the freedom of init system?
Edit: I'm asking this because I came across this blog - What is systemd and Why Should I Care? and also because Guix uses shepherd, and I'm not sure how I'll be affected.
The more you learn about the original vision,. .. it is kind of terrifingly brilliant and powerful. The architects knew exactly what they were doing. That's why in the late 70's they tried the keep it from the public! (you can send thx to rms - he opened it up for us)
