Influence generating of the (leapp) upgrade initramfs
The upgrade initramfs is used during the crucial part of the upgrade,
in which the original rpms are upgraded, configuration of applications
are migrated, etc. To be able to boot into the leapp upgrade environment
correctly, it is expected all needed drivers, configuration files, ... are
included inside the upgrade initramfs. Produce this message with
expected content to influence the upgrade initramfs.
If some specific rpms or content is required to be able to build the
upgrade initramfs, see the <container-model>.
Note: The built initramfs is composed of stuff for the target system.
In example, if you are on RHEL 7 and plan the upgrade to RHEL 8, you need
to provide content (e.g. drivers, dracut modules) compatible with
RHEL 8 system.
