[Q] Does NANDROID backup your kernel, and if not... topic

Hi,

I've been Googling this question for the past 30 minutes and I keep seeing conflicting answers. I own an I9300 but this is a general question - does a NANDROID backup your kernel as well and can CWM restore the kernel from the NANDROID backup?

If not, is there any method to backup your kernel separately? (I do not want to count on online files for my stock backups regardless of reliability, so please keep your answers to the point, I know you can download stock kernels)

Thanks in advance,
