Hi all, I noticed Debian folks reimplemented the old good update-alternatives command from Perl to C. That means your-favourite-program (like awk or vim) will no longer depends on Perl in openSUSE. Good think is - new implementation is backward compatible, so no changes in %scripts are required, no reinstallation and so. And what is better, the simple %post update-alternatives --install %preun update-alternatives --remove calls would work without a problem, which is the most common use-case. I found only two notable differences: 1.) more verbose by default - considering to change it, as all things are already logged to /var/log/alternatives.log zypper remove java-1_6_0-openjdk Removing java-1_6_0-openjdk-1.6.0.0_b18-1.29 [done] Additional rpm output: update-alternatives: warning: alternative /usr/lib64/jvm/jre-1.6.0- openjdk/bin/java (part of link group java) doesn't exist. Removing from list of alternatives. update-alternatives: warning: alternative /usr/lib64/jvm/jre-1.6.0-openjdk (part of link group jre_openjdk) doesn't exist. Removing from list of alternatives. ... and much more 2.) Don't allow the same slave alternative in more than one - bnc#648260 - even if it's a bug in openjdk packaging I prepared package is in OBS - home:mvyskocil:update-alternatives/update- alternatives [1]. Please test (at least) your package with newest update- alternatives and bug me in case of troubles, thanks.
