[packagekit] Questions about install-signatures, what-provides and repo-set-data

[Mounir Lamouri]

Hi,

I would like to have some informations about these 3 functions.
This is to be sure portage backend can forget them.

* install-signatures
Signatures are GPG keys which are "signing" packages for security reasons ?
So, signed packages are the ones named "trusted" ?
As far as I know, the only security in Gentoo is md5sum of the ebuilds/tarballs
and they do not need to be installed so this function probably doesn't need to
be in the backend.

* repo-set-data
I really don't get the meaning of this function. According to the example, user
can set the download-url of a repository ?
I suppose if I can't get what is the use of this function it's a good reason to
say I don't need it ;)

* what-provides
I don't see an easy way to get those informations. I suppose it is used for
missing codecs ?

Thanks,
Mounir
