Bruce,
OK, so that's fair enough, but is there any real reason for Devuan to behave as anything other than a normal Debian derivative?
When they were trying to "eradicate every last work by Mr. Pottering", including libsystemd0, that wasn't going to work, since Debian doesn't really have a workable way to have two versions of the same package, differently linked (well, not without an explosion of foo-without-libsystemd packages, which wasn't going to get past the ftpmasters).
Now that they seem to have rowed back a little from that position, it seems like the main thing is the maintenance of alternative packages, and the testing of the coherent whole, both of which could be pushed upstream to some extent.
If all the packages could be pushed upstream, then Devuan might even be able to be a Debian Blend, or perhaps even a Debian Pure Blend, which would then allow them to release in a timely manner. Even without that, I'm sure that there are Debian users that would appreciate the option of using the main components like eudev.
Looking for evidence of attempts to package eudev for Debian, this is about it as far as I can see:
https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fbugs.debian.org%2Fcgi-bi...
and
https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Flists.debian.org%2Fdebia...
neither of which have gone anywhere since.
Given that the packages now exist, it ought to be pretty trivial to upload them to Debian. That is likely to attract more people to use them, resulting in more effort being available to keep them maintained in future, so everyone wins.
If there's some reason that they cannot be uploaded to Debian in their current state, then it would be helpful to have the ITP ( https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwiki.debian.org%2FITP ) in the BTS ( https://ancillary-proxy.atarimworker.io?url=https%3A%2F%2Fwiki.debian.org%2FBTS ), with blockers being described, providing somewhere to discuss how to address that situation.
Cheers, Phil.
