kernel image path

[Sumit Kumar]

Hi Valdis,

Thanks for the quick reply.

I wanted to find out where the kernel images are stored to check their 
size.

My local kernel repository size has inflated to around 14 GB after 
building kernel a few times. I was wondering if it keeps previous images 
as well which could be taking a lot of disk space. By looking into arch 
folder it seems kernel image takes around 8 MB. Max. space is used by 
drivers folder - I guess its the object files from all the drivers. I am 
again left wondering if building kernel drivers multiple times keeps the 
older driver object or replaces it with newer one.

I am little bit short on disk space right and hence needed to clear few 
things out.

Thanks and Regards,

Sumit
