greetings,
had problems burning a dvd for 6.4, so i burned a livecd and installed it from boot menu to ext4 /dev/sdb3.
during install, i defined mounting of /dev/sdb5 as /home and a second partition /dev/sdb6. both are ext4.
first boot went well, set up user, rebooted.
rebooted level 5, logged in as user, all looked good.
rebooted level 5, logged in as root, made changes to /boot/grub/grub.conf to boot other os.
rebooted level 5, logged in as user, opened terminal, su to root, tried to 'yum update', all mirrors failed. did not think of trying pings to see if was connected to internet. which could have explained failure. my bad.
exited from root, closed terminal, rebooted to other os, logged in as user, opened terminal, pinged several sites, pings returned ok. closed terminal,
rebooted, to centos, crashed during level 5 boot.
shutdown system, rebooted level 3, boot crashed again.
error message;

i ran a search for;
dracut Warning: No root device "block: /dev/disk/by=uuid/
at centos.org
only errors show where raid related.
another thing that is strange, boot is looking for a device that is not listed in /dev/disk/by-uuid.
