Commit 018a0c9a7164f ("Dh_Lib.pm: Fix warning from `cp -n`") uses cp's --update=none option which has been introduced rather recently, namely in coreutils 9.3. Older versions of cp do not understand this option, complain and refuse to operate. For instance dh_update_autotools_config fails with older coreutils: ,---- | $ cp --version | head -n1 | cp (GNU coreutils) 9.1 | $ dh_update_autotools_config | cp: option '--update' doesn't allow an argument | Try 'cp --help' for more information. | dh_update_autotools_config: error: cp -a --update=none --reflink=auto config.guess debian/.debhelper/bucket/files/ec2577614252326f889df1de97b9a457c03a9a94811048563c211a44496d8ba3.tmp returned exit code 1 `---- This is obviously bad for backports, more urgently it is going to make many packages FTBFS on hurd-i386 which is stuck at coreutils 9.1-1. I will open a separate bug on coreutils for giving the questionable advice to use the --update=none option.
