Replying to [comment:2 zooey]:
> It really depends on what you mean by incorrect - as it seems, you have
compared the sonames from haiku with the ones on Linux. But the BSDs for
instance have a different soname scheme (incrementing the numeric suffic
for every release).
Soname is defined by the a package and it's OS independent. I'm talking
about open source software available on various operating systems. It
looks like FreeBSD (ports) uses the same rules, for example
[http://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-9-current/All/icu-4.3.3.tbz],
[http://ftp.freebsd.org/pub/FreeBSD/ports/i386/packages-9-current/All/ncurses-5.7.tbz].
For some reason libjpeg has different soname in FreeBSD.
> The soname scheme currently used in haiku simply uses the libraries name
+ ABI version for the soname.
Many 3rdparty software use libtool. The major version number is changed
only if ABI has changed.
[http://www.gnu.org/software/libtool/manual/html_node/Updating-version-
info.html]
> It is hard to tell from their past releases, but is libjpeg 8.1 really
going to be ABI compatible with 8.0? Please tell if you've found a point
of reference for that.
> Of course we could still name it libjpeg.so.8 and then name the next
release libjpeg.so.8.1 if it is not compatible. But I personally find it
pretty cumbersome to try and track ABI compatibility for libs that do not
care to document their ABI compatibility policy.
In my opinion 8.1 will be binary compatible with 8.0, but there is no
guarantee. We should trust to package maintainers and believe that they
change major version if they break binary compatibility.

the library?
Soname should match the ABI version instead of software version.
Summarizing. I prefer to use original soname provided by a package
maintainers instead of introducing own.
