It should not happen any more moving forward though, as we will only ever release ONE noarch file in future, regardless of it they built slightly differently from the builders. OK, the only difference on these RPMs is the signature (it happened at a different time, by one second). If you look at rpm -qpi you will see one of them was signed at: Signature : RSA/SHA1, Mon 26 Mar 2012 08:36:33 AM CDT, Key ID 0946fca2c105b9de the other: Signature : RSA/SHA1, Mon 26 Mar 2012 08:36:32 AM CDT, Key ID 0946fca2c105b9de (they were 2 separate files, produced in two separate build trees, and therefore have 2 separate signature times) However, if you do this to each of the files to remove the signatures: rpm --delsign python-slip-dbus-0.2.20-1.el6_2.noarch.rpm then do an md5sum, you will see that underlying (and unsigned) rpms have identical md5sums of: [johnny@m4500n 6.5]$ md5sum python-slip-dbus-0.2.20-1.el6_2.noarch.rpm 8cb0c87fd4942673c79c304d3c29aedb python-slip-dbus-0.2.20-1.el6_2.noarch.rpm [johnny@m4500n 6.5]$ cd ../6.4/ [johnny@m4500n 6.4]$ md5sum python-slip-dbus-0.2.20-1.el6_2.noarch.rpm 8cb0c87fd4942673c79c304d3c29aedb python-slip-dbus-0.2.20-1.el6_2.noarch.rpm Also, the content of each RPM is identical at these values: 511a4571af6e42e130c43bfff2507863 ./usr/lib/python2.6/site-packages/slip.dbus-0.2.20-py2.6.egg-info 01bb823d18266732b2cb24d7ea1d693b ./usr/lib/python2.6/site-packages/slip/dbus/__init__.pyc 77ec375c396560fc4dd8bf0160831cfa ./usr/lib/python2.6/site-packages/slip/dbus/bus.pyo 426ba8cb64e3ce60a40042ce961faebc ./usr/lib/python2.6/site-packages/slip/dbus/proxies.pyo 5d5bab55941cb57d18bddb09dc1993bb ./usr/lib/python2.6/site-packages/slip/dbus/proxies.py 01bb823d18266732b2cb24d7ea1d693b ./usr/lib/python2.6/site-packages/slip/dbus/__init__.pyo 89073c18b01d301eefd7169fc08360fa ./usr/lib/python2.6/site-packages/slip/dbus/bus.py dc7e59367bab048fc3bca4fc94e2f5fc ./usr/lib/python2.6/site-packages/slip/dbus/mainloop.pyc 3010ee109154bb35be8458f1e0ab65e1 ./usr/lib/python2.6/site-packages/slip/dbus/polkit.pyo 2af7a635fd80074aa75a095310cbdf96
