Apologies if this should be well-known, but I couldn't find anything! Situation: a system in a remote location, with no KVM, IPMI or iLO, and therefore no console access, only ssh. Multiple kernels listed in grub.conf. Is there a way to reboot temporarily into one of the other kernels listed in grub.conf, without changing the default= line, so that a subsequent reboot will default back to the original kernel? The problem I have is that having changed the default= line to select a kernel that doesn't boot properly, I need to have someone visit the console in order manually to select the working kernel again. I would like to avoid that situation if possible. Thanks, Tony -- Tony Mountifield Work: tony at softins.co.uk - http://www.softins.co.uk Play: tony at mountifield.org - http://tony.mountifield.org
