  Actually, that's a fact.

  What could they possibly do of any harm to your system systemd unit
files, that is plain ASCII config files?

 [alessandro@wksrn05 ~]$ du -sh /etc/systemd /lib/systemd/system/
44K     /etc/systemd
464K    /lib/systemd/system/
 [alessandro@wksrn05 ~]$


  That's the *huuge* ammount os "system resources" they occuply on Ascii
(Devuan 2.0).

How does this compare with forking and maintaining hundreds of packages
just to have them not install those files?

  Everyone busy maintainig and developing Devuan already knows how
that's to be done.  They already did it for a lot of packages to take
away more than just systemd unit files.  Of course you're always welcome
to step in to do the gritty work and take maintainership of a few,
important packages to take away those "dangerous" unit files.

  And I wish we were living in a world where the only struggle was
advancing science, knowledge, free software and landing on far away
planets and explore the galaxy.  Reality is quite a different story,
though, and it's not the Free Software people's fault.

  How much did you read of the code of the packages you have installed
in your system?

How can you be sure the only piece of software that's not to be trusted
is systemd0, where does this obsession come from?

  Yeah, that's the spirit: patch up and contribute, maybe we'll end up
having a totaly Debian- and systemd-independed distribution and lots of
people would be grateful.

  But if you don't, at least please stop the whining.
