Re: Major number in library package names



Would be a very good idea, but it will not happen, as it has been
suggested numerous times and fallen into /dev/null. Nevertheless my
2 cents below.

Splitting out the shared libs in its own subpackage and including the
major version by default is a very good idea, as it obsoletes the need
for creating compatibility libs (backward and forward!).

The only drawback is orphaned libs when no other app need them, which
is the same for compatibility libs as created today.

That drawback is reduced to zero, if all such "disposable" packages
would

Provide: runtime-package

or something like that, that a package-garbage collector could
identify and throw them out of the system when they are not in use
anymore (and apt/yum would get them back if an app to install would
require them).

This also helps migrating apps from on lib version to another. No need
to rebuild all dependent packages the moment a lib major version get
bumbed up.

This model stems from Mandrake and they have been successfully using
it. Have a look at recent ATrpms package to see some Fedora
implementations :)

100% with you, the names chosen for the shared libs should never
explicitely enter the dependencies! rpm already does the right job.

But having the major library version in the name solves other issues,
as outlined above :)
