Description

Since rpm version 4.15, rpmbuild supports a new option --scm. I would like to check whether this could be leveraged to implement "quilt setup" in a different way, which would possibly be faster and more robust.

Goals

According to the documentation, it is possible to pass --scm=quilt to get %autosetup to call quilt instead of patch. I want to test what exactly happens when you do that and if and how quilt could use that option for an alternative implementation of the setup command. If this works, this could solve a number of issues, like quilt setup breaking on internal implementation changes on the rpmbuild side, or the need to perform md5sum of all source files to figure out the patch sequence.
