I've got two questions that I'm curious about. One of for the maintainers of CentOS and the others is for the community at large. 1) At what point does a third party app get rolled into the production repository (not sure if I said that correctly)? Example: At what point is it OK for the OS maintainers to adopt a newer version or PHP, MySQL, Apache, etc.? 2) I have read mixed opinions with how to install a database server. Some articles say install it via YUM for compatibility purposes; while others say install it from a tar ball or source to ensure other packages do not try to upgrade and break the database. What are your thoughts? I plan on running a web server farm for a CMS/DB that needs to have a five 9 uptime.
