Hello everyone. I've recently been assigned admin duties for servers running Plesk on CentOS. Both Plesk and the OS were outdated, so I have run 'yum update' to upgrade to CentOS 4.5 and used the Plesk updater to update to Plesk 8.1.1 and overall it was a fairly smooth process. I've noticed that /etc/yum.conf contains this line: exclude=kernel* sendmail* I understand the "sendmail*" entry, since Plesk uses Qmail. However, I do not understand why the kernel is excluded. One server is running the kernel "2.6.9-42.0.10.ELsmp", others are running "2.6.9-42.0.3.ELsmp", but currently, the latest kernel is "2.6.9-55.0.2.EL". Does anybody know of a good reason why I can't upgrade to that kernel? Does the Plesk install software add that line to yum.conf, or would it be something that the previous admins of these servers did? Has anybody else already upgraded to "2.6.9-55.0.2.EL"? If so, did you encounter any problems? Thanks.
