Greetings,

Installing Compiere ERP on SLES 9 /64, which requires hacking the Kernel a little...

How do you backup the kernel?

If you update the kernel, you have to re-hack it right?

if the Hacks have a problem, after updating the kernel, how do you restore it?

This is a test situation, in production, we will have P-Series, with a test partition we can properly test prior to going live with the update...

Thanks

I am not sure if I understand what a hack is

But since SUSE is a rpm based system, you can always have the rpm as a backup. If you would like to test a new kernel, you may want to install it in parallel to your old kernel. This is no problem for a manual kernel installation (copy bzImage to /boot), but also no problem with kernels on rpm basis if you delete the actual kernel from the rpm database (rpm -e --justdb <kernel-rpm>). The kernel selection is done from the bootloader.

So what's my point: you don't need to backup if you do not replace your kernel.

I hope I understood you correctly
