Subject: [PATCH 51/60] Introduce two functions for listing which packages are
|
|
leapp packages.
|
|
|
|
* rpms.get_leapp_packages() library function returns the leapp packages which ship the leapp
|
|
components.
|
|
* rpms.get_leapp_deps_packages() library function returns the leapp deps meta packages which list
|
|
the requirements of the associated leapp packages.
|
|
|
|
This function can be used as leapp-installation-packages-getter.
|
|
Refactoring of other actors using it will be done later.
