I've been using it since Fedora 15, I find it easier to use to troubleshoot boot and service startup problems. systemd-analyze blame/plot are quite useful for boot performance optimizing. The journal on Fedora these days is persistent, on CentOS it's volatile with rsyslog running by default; but I like being able to journalctl -b-2 or b-3 to view previous boots, or point all systems to a single server, and sealing the journal logs against tampering, etc. It's certainly different, but wasn't onerous to get used to, and these days I prefer it. > >> perspective, but anything really new that's hard to backport likely >> isn't in that kernel.

It's almost certainly a hardware problem given the numerous identical setups not having this problem. But, seeing as it panics every 30-40 hours, it can hardly be much worse with a new kernel running for a couple days... but my bet is there'd be no change. -- Chris Murphy _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
