Step-by-step – Build Kernel Fedora 37 Guide

Configuring

5. 5. Configuring Kernel

   So now to Configure Fedora Linux Custom Kernel
   First, access the Kernel Source with:

   cd linux*

   Then copy the current Configuration File into the New Kernel Source:

   sudo find /boot/ ( -iname "*config*" -a -iname "*`uname -r`*" ) -exec cp -i -t ./ {} ;

   mv *`uname -r`* .config

   In case of a Chrooted System instead you may look up the available Kernels with:

   ls /boot | grep config

   The grep Command refine the output List showing only the entries Matching the Keyword.
   Again if needed then fix the Configuration File editing it with nano and commenting out the Line like:

   sudo nano .config

   Use Ctrl+w to search for “CONFIG_SYSTEM_TRUSTED_KEYS” on nano.
   And comment out like:

   #CONFIG_SYSTEM_TRUSTED_KEYS

   Ctrl+x to Save & Exit.
   Else to make a Custom one then reconfigure the Kernel (Only for advanced Users) with:

   sudo make menuconfig
