Description of problem:

Having just done a yum update, I've had to install gphoto2 because the
latest version of sane-backends supports a gphoto2 backend. This is
wrong. If I don't plan on using that backend (which I don't), then I
shouldn't be forced to install a package that I don't want or need.
Is there *really* a dependency there? I.e., will sane applications not
work at all, even with a different backend if gphoto2 is not installed,
or will just that backend not work? If it's the former, then a serious
redesign is needed. Perhaps the gphoto2 backend could be split out
into a separate package. If it's the latter, then there shouldn't be
a dependency present.

For those of us trying to runa minimal system, dependency creep like
this is a real problem.

Comment 1 Nils Philippsen 2006-03-14 10:43:25 EST
The problem is that "soft dependencies" are not yet implemented in RPM (at least
for the version in FC4). So while the dependency on gphoto2 isn't strictly
necessary if you don't use that backend, it's the best we have, at least as long
as I don't split off backends into their own subpackages, which I don't want to do.

Paul, can you give some insight on RPM and soft dependencies, please?
