channel protocol ugrade problem

I am packaging a few php-pear packages for Mageia and Mandriva. When I run from a shell as root pear list-upgrades I see this message: WARNING: channel "pear.phpunit.de" has updated its protocols, use "pear channel-update pear.phpunit.de" to update We don't want to upgrade the channel from the internet, we use (as does Fedora and Opensuse) in a small package the following script to use a local xml file: %post if [ $1 -eq 1 ] ; then %{_bindir}/pear channel-add %{_datadir}/pear/packages/pear.phpunit.de.xml > /dev/null || : else %{_bindir}/pear channel-update %{_datadir}/pear/packages/pear.phpunit.de.xml fi when upgrading the package that runs this script it reports that the channel has been upgraded, but pear list-ugrades still reports the wanrning When I run pear channel-update pear.phpunit.de manually the channel actually gets upgraded and the warning disapears. What does actually happen when I run pear channel-update pear.phpunit.de ? Which file(s) gets modified? -- Best regards Thomas Spuhler
