@Fajar, your advice is much appreciated.

Some small comments below.

I had looked at the dkms manual page as well as a number of articles and
Q&A for dkms, but the information on dkms is not really clear and complete.
I will try some experiments and report back.

I see your point. I have 2 or at most 3 machines to look after, which is
why I can afford a rather artesanal approach. But I can see that reliable
deb packages could simplify matters. The spl/zfs installation is much more
complex and invasive than something like dovecot, so it is more difficult
to handle version transitions cleanly. I think I need to learn to love the
Debian packaging methodology, which has always seemed mysterious to me. It
also seems to me that some issues with, for example, dkms.conf, were still
present even in the official ZoL Debian packages.
