I found out that all my debian machines switched to systemd without my consent, with just a standard apt-get ugrading.
I despise that decision.
I did not follow the latest discussion about it, I was left with the impression that it would have been installed only if needed, but evidently I was wrong.
Can you get back? Time to toss Debian? I hoped not, I know of other fellow developers who switched distribution, but Debian is Debian.
Remove systemd and sysvinit (which is now a transitional package) and put back sysvinit-core back. I had the fear that I bricked my laptops, but it still works. For how long? I don't know.
I'm very very sad about this. If I think of GNU/Linux I think of Debian, it has been with me since 68k times, when potato was cool. Debian made a very bad decision.
Something newer than ol' sysvinit? Something modern, fast, capable of parallelism. Yes.
But something portable, light, secure, which is not a dependency hell, which does one thing. In other words, something in line with the Unix philosophy.
Not the enormous pile of rotting shit which is systemd. When I removed it, I freed almost 13Mbytes from my system. I am relieved, but it shows also how big that pile of crap is.
So, for now, Debian can stay with me, I hope it will be for a long while. Long enough that debian will revert or systemd will go away.
