Kubuntu CI performs QA on whether all patches that are under version control are also listed in the debian/patches/series file. Sometimes it can be desired that a patch gets disabled but not removed (e.g. debian patch) making it necessary to ignore warnings about missing patches.
Ignore Rule File
Ignore rules are placed next to the series file in debian/patches/ and named ignore.
Ignore Rule Format
The ignore file has exactly the same format as the series itself. Each line contains one patch name that should be ignored. Lines starting with a hash character are comments. Empty lines are ignored.
$ cat debian/patches/ignore # Debian specific defaults, we have our own patch for ours. debianize_akregator_default.diff
