Excellent - just what I was looking for. Thanks!

Subject: [CentOS] One-time reboot into alternate kernel?
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
