I have read on many site that having a backup is good but this step is optional. __________________ Only if I could understand the man pages Registered Linux user #492640 OS: RHEL4,5 ,RH 9,Ubuntu

It's good to have because now you can just copy the .config file to a new kernel directory and issue make oldconfig instead of having to sort through the whole thing like you just did. Keep in mind that this is only advisable for minor version changes in the kernel. See this Gentoo kernel upgrade guide for more info.

I always keep a backup .config file so when I compile a new kernel I'll always have a spare if the original should somehow get lost or corrupted. __________________ CRUX 2.5 + IceWM Registered:#371367 New Members: click here
