While it is understood that it is not the responsibility of the CentOS Team to teach the community, nevertheless, it would be helpful if the CentOS Team (or others in the know) could list a handful of packages that are among the 600 Johnny reports as requiring attention in C6, preferably some that won't even compile, others that require comparison with the upstream binaries to note the problem. N.B.: . for C 3, 4 and 5, to date, we've watched nearly 4,000 (albeit it was hard to see anything other than the outcome, which was GREAT) . many of us are ready and would like to do one, so please tell us which packages in the corpus will result in a failure in a stock/vanilla build environment. . perhaps somewhere between C6 and C7 some will pass muster. THANKS for your consideration of the use of this widely used method of teaching MDs, DVMs, DDSs, et al. kind regards/ldv/vaden at texoma.net
