===  FAQ  ===

Q: A Kernel upgrade broke my tuned bootloader settings.
   How can I edit them manually?

A: See below for an overview of bootloader related config files.
   You can also set LOADER_TYPE="none" in /etc/sysconfig/bootloader to keep
   the system from touching your individual boot config at all.
   *** WARNING *** after a kernel upgrade you may need to update your boot
   config manually (e.g. with lilo).
