new package provider: paludis

package provider: paludis

This patch changes the default package type for gentoo, which results in backward-compatibility issues. I'm not willing to accept such a patch unless José, who has been the Gentoo maintainer, signs off on it.

Also, this creates a new parameter that no one else can use. Do other package types have this capability? Should this be a provider feature?

the provider script from the first post, minus the extra parameter, minus default for gentoo

As for the extra parameter, how about adding a parameter to package like pkgmgr_extra_opts which one would use to pass a string to the package manager which would get appended to the command line call, thereby passing extra options specific for one package manager? So that e.g.

package{ "postfix":
   ensure => absent,
   provider => paludis,
   pkg_mgr_extra_opts => "--with-unused-dependencies"
}

would work as intended by the original patch author.

This provider causes failures on non-gentoo systems because it requires the 'Paludis' library (see #956).

In order to make this work well within Puppet, you need to create a 'paludis' feature that tests whether the Paludis library is present and only have the provider be suitable in that case. See lib/puppet/feature/ for example features, then you should have something like this:

confine => Puppet.features.paludis?

to test whether the feature is present.
