Description Jakob Schiotz 2005-03-31 00:33:42 UTC

I just looked at the kernel upgrade guide (see URL).  I think that a very useful trick should be added to section section 5 option 2 "Manual configuration":

Copy the .config file from the previous version of the kernel, and then run "make oldconfig".  You will then be asked about all new options in the kernel.  You may want to run "make menuconfig" afterwards to check or adjust the configuration.



Reproducible: Always
Steps to Reproduce:
1.
2.
3.

You can enable Kernel .config support, so you can e.g.
zcat /proc/config.gz > .config
