The original cgcs-patch is rpm based which requires a complete re-write to work on ostree/dpkg systems like Debian. The code has been forked, since the older Centos env and python2.7 are end-of-life. Forking the code allows all new development to not require re-testing on Centos. The debian folder under cgcs-patch has been moved under sw-patch Renaming and refactoring will be done in later commits. pylint is un-clamped in order to work on python3.9 Some minor pylint suppressions have been added. Test Plan: Verify that this builds on Debian Verify that the ISO installs the new content on Debian without breaking packages that import cgcs_patch. Verify patching service runs on Debian Co-Authored-By: Jessica Castelino <jessica.castelino@windriver.com> Story: 2009101 Task: 43076 Signed-off-by: Al Bailey <al.bailey@windriver.com> Change-Id: I3f1bca749404053bae63d4bcc9fb2477cf909fcd
