The default /etc/munin/munin.conf includes a section for monitoring the hostname of the Fedora build host. It still actually monitors 127.0.0.1, but the name is totally wrong and confusing. Two options exist: #1 oneliner sed/perl hack in specfile to use "localhost" as defalt name #2 or more interestingly, tweak the %post script to adjust it dynamically Option #1 has the benefit of being simpler and does not alter the verification status of the rpm database. Whereas, option #2 produces more friendly default html, but at the expense of immediately flagging the newly installed package as modified.
I thought I had already put in a sed to fix that, but I guess not. ;) I will investigate and see about a solution. Thanks for the bug report!
This should be fixed in the new version I just fired off builds for in the build system. If you see the bug reappear after updating to the next release, please open this bug or file a new one. Thanks.
