The build host name is included in some files in the munin and munin-node
package (in Tumbleweed and Leap).


# rpm -qi munin | grep Host
Build Host  : build33

"build33" leaks into the following files:

munin - /etc/munin/munin.conf:
    [build33]

munin-node - /usr/lib/perl5/vendor_perl/5.24.0/Munin/Common/Defaults.pm:
    our $MUNIN_HOSTNAME   = q{build33};

munin-node - /etc/munin/munin-node.conf:
    #host_name build33


This causes at least two problems:
a) you ship a munin.conf with "random" content
b) the build is not reproducible

Please use a fixed value for the hostname. "localhost" works perfectly for
small setups, so it might be a good choice and matches "address 127.0.0.1" ;-)
