HI,

I've got a root server (debian woody) with ssh access in a remote location. Now I'd like to compile and install a new kernel, but I fear the machine might not come up again and then I'll have to pay those guys for intervention.
Is there anyway to make sure the kernel will work before actually rebooting the machine ?
Or is there any failover mechanism I could use such as "if new kernel doesn't boot boot the old one" ?
I'm using lilo by the way but could of course switch to grub in case..

any hint would help.


thanks

Well first of all, I'd recommend running a screen session first while compiling.. just in case you lose connection to the host, it won't kill your kernel recompilation.

Secondly, there really isn't a failover mechanism that I know of. If you setup your remote host to boot into a new kernel and it fails while booting, well, you have to get someone to intervene somehow. Just don't screw up your recompile and you'll be ok..
