Howdy Joe, We never could finalize an ideal migration plan to rename mysql55 to mysql55u. There are too many variables involved with trying to require/recommend a service restart. We decided that the only safe action is no action. The conflicting rpm "mysql55" is a metapackage to pull in the other SCL rpms, and it is still at version 1; based on the past release dates [1][2][3] and the published SCL lifecycle [4], we believe that EL5 will reach EOL (2017-03-31) [5] before this version gets high enough to cause update issues for IUS users (our mysql55 rpm is at version 5.5.44). To be absolutely safe, users can add "exclude=mysql55*" to the file /etc/yum.repos.d/CentOS-Base.repo. This step would be required if Red Hat later adds an epoch to the mysql55 SCL rpm. Likewise, a user that wants to use the mysql55 SCL rpm but have IUS enabled should add "exclude=mysql55*" to the file /etc/yum.repos.d/ius.repo. Our concerns are reduced even further by a number of other factors. * SCL rpms for EL6 are provided in a separate channel/repo, so this problem only affects EL5. * Discussion on mailing lists indicate that Red Hat will be prefixing future SCL metapackages with "rh-", helping prevent naming conflicts. * Over time our packages that are missing the "u" suffix will reach EOL until all our packages follow the new naming scheme. For good measure, we did add a note about the conflicting package on our website section comparing IUS packages to SCL packages [6].
