If that were the case, then the kernel update from the CentOS repo should not have been allowed by default.
Anyway, so far, no untoward errors have been noticed in a fresh SME8 install with SAIL v4.0-58 along with it's fixes, fully yummed uptodate.
Considering the number of changes in v8.0 that have been available, it would be nice to have a fresh v8.1 ISO rolled out with a script to update an existing ISO as well.
