[ale] Creating a failsafe boot

[jb at sourceillustrated.com (John Wells)]

Guys,

Just purchased a dedicated server and will be installing Xen shortly. In
my experience, Xen installs are not without their share of kernel panics
and woops! moments.

I suspect the only way to do this is to be *really* careful, but is there
any sort of mechanism to cause grub to boot a failsafe kernel after a
certain number of attempts at booting another kernel? Without physical
access, I have to be sure this box comes back up at some point.

Thanks guys.

John
