DNFWorkaround is used to register scripts, that have to be executed to apply modifications to the system,
|
||
|
|
just before DNF performs a transaction in order for it to succeed.
|
||
|
|
|
||
|
|
As an example in the case of the RHEL7 to RHEL8 upgrade, we have to execute a script to fixup the way how
|
||
|
|
yum and dnf symlinks are created as they cannot be replaced by RPM. To solve this we have created the
|
||
|
|
handleyumconfig tool in the system_upgrade/el7toel8 repository and register the workaround with the
|
||
|
|
registeryumadjustment actor.
