I still encounter problems. When running a kernel without initramfs one
or another way vdev refuses to start because /var/log/vdev is not
writable. The only way to make it start is to use /dev/null as logfile
and restart it in rc.local.

That is some or other form of FUD. I hear these "it's too
dependent of systemd" arguments quite often here, but I don't think the
Gentoo folks would have used eudev if they were fearing the same. Devuan
is 99% Debian, that is even more a big threat if you consider the
systemd imperialisation.

No, but I fear vdev is stillborn. It's an orphaned project for the
moment. Don't get me wrong, I'd rather run vdev than another device
manager. The thing is: we may be able package it and to run it in
Jessie (as we tried last week), but will vdev still work in a year or so
if there's no development of vdev itself?

I agree, but unfortunately nobody has the time and the skills to pick up
vdev and to continue its development. I have neither the time, nor the
skills unfortunately, otherwise I would certainly have participated in
the project. For the moment Devuan is still equipped with udev-systemd,
so Devuan is very very dependent on the systemd guys. Just something
nobody wants here.

And with "freedom of choice" in mind: indeed, it would be nice if eudev
would be available anyway, whether vdev will be continued or not.
