This is irritating: I've got a server I just upgraded to 5.4, then rebooted, only to discover that it just *sits* there at the grub boot menu. I looked at grub.conf, and uncommented hiddenmenu (which should have been done long ago). It *still* sits there when I reboot. Any clues, folks? mark grub.conf: #boot=/dev/sda default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-164.2.1.el5) root (hd0,0) kernel /vmlinuz-2.6.18-164.2.1.el5 ro root=LABEL=/ rhgb initrd /initrd-2.6.18-164.2.1.el5.img title CentOS (2.6.18-164.el5) root (hd0,0) kernel /vmlinuz-2.6.18-164.el5 ro root=LABEL=/ rhgb initrd /initrd-2.6.18-164.el5.img <snip>
