Re: systemd-free?
Right, so if we're all relaxed about having libsystemd0 sitting on the disk, and if we're capable of remembering that Debian allows one to choose the init of one's choice, what exactly is the difference between Debian with sysvinit installed, and Devuan?
Note: init-system-helpers -- a package specifically created to allow one to switch between inits in Debian, which of course is also used in Devuan.
Is the answer to that things like udev rather than eudev?
If so, is there anything to stop eudev being uploaded to Debian? (I note that the ITP has been fallow since 2014: https://bugs.debian.org/765971 )
