|

Hi all,
I'm just wondering if there is any good trick to this.
I have a mythtv box I need to do major upgrades to. This involves getting and rolling a new kernel..a few versions in between.
It took me forever (and I can't find my notes) to get all the kernel parameter, and a ton of them are modules....I'm wondering if there is a quick way to ensure I get them all set for the next kernel.
I usually use make menuconfig to set up the kernel....but, it seems this set up changes every time you do a different kernel (things are arranged differently, etc).
In this method...it is also a PITA to go through most every possibility, and hitting Help to see what the module name is if you select M....and sometimes in the help they don't say what it even is...
I though about trying somehow, to go directly into the .config that it generates...but, in there it doesn't say what the module names are that are generated if you set it that way....
So, I don't see an easy way to go through my autoconfig.modules file, get the names of the modules I have there...and translating that into a new kernel config...
Is there something I'm missing? Is there a tool or method ya'll use to more easily keep the same settings between kernels...and just have to worry about the new things you got the kernel for?
Thanks in advance...

cayenne,
Copy the .config file from the old kernel to the new kernel
In the new kernel, run
It will silently delete options that have been removed, copy over unchanged options and ask you about new things.
The bigger the gap between the old and new kernels, the more questions you get asked and the more scope for errors.
When its done, you have a legal .config file for the new kernel. Look it over in _________________ Regards,
