FAQ

Q: Kernel upgrade break my tuned bootloader settings, I want edit it manually.
A: set LOADER_TYPE="none" in /etc/sysconfig/bootloader. Hint is used 
/boot/vmlinuz and /boot/initrd symlinks as files which is already point to 
actual kernel. WARNING after kernel upgrade you must update also configuration 
manually, otherwise you cannot boot.



Configuration files for bootloader (if you want manually edit it)

/etc/sysconfig/bootloader - contain various settings for bootloader and is used 
by perl-Bootloader

for grub (x86*) or trustedgrub -
  /boot/grub/menu.lst - main configuration for sections
  /boot/grub/device.map - mapping of real device to grub device
  /etc/grub.conf - batch file for grub if you need update your bootloader 
location
  
for lilo ( x86* or ppc) - 
  /etc/lilo.conf - main configuration file

for elilo ( x86_64 or ia) -
  /etc/elilo.conf - main configuration file
  efibootmgr - utility for efi labels
  /boot/efi/efi/SuSE/elilo.conf - configuration after elilo preprocess, use 
only if elilo break original configuration, in other case edit directly 
elilo.conf in /etc

for zipl (s390)-
  /etc/zipl.conf - main configuration file
