Rudder

#7556 introduced a test to check for non-applying patches, which works fine in rudder-agent, but does not in rudder-jetty and rudder-agent-thin, because it relies on the "$(FIND)" Makefile variable, which is not set in those packages SOURCES/Makefile, resulting in this error:

03:42:10 # Make sure there were no rejects
03:42:10 test ` . -name \*.rej | wc -l` = 0
03:42:10 /bin/sh: 1: .: -name: not found

This error is however not sufficient to break the build, because all we check is that the number of lines output is equal to 0... which it is, as the error appears on stderr.
