(The numbers are directly fed into libtool's -version-info argument.) As
you can see, the CURRENT number was decreased, which, according to
common libtool sense, is not something that one should normally do. Why
do I care? Well, I happen to be active in toying with system tools
(especially the ones I have to use sooner or later), as well as distro
packaging, with a preference to get things right.
Unfortunately, I was unable to convince the kmod people of this fact.
Kay Sievers and Lucas De Marchi's argumentation is that (a) kmod is
linux-only and (b) there has 'never been a libkmod.so.2' before, or even
something about (c) not caring about GNU/"the mess that libtool is".
Hopefully your intention is only to illustrate what projects should
not do and not to submit a patch. This libkmod project seems to be
less than two months old and perhaps the developers still have a bit
to learn about library versioning.
While libtool does compute the name to apply to the library (using ELF
rules), build-time (ld) and run-time (ld.so) linking is done via
standard system tools and so they determine how the naming gets used.
ELF is where the rules come from, not libtool. Libtool tries to make
it easy to follow the ELF rules while working as best as possible with
other schemes.
