+** Other installed bootloader **
+
+Please pay attention to the hook scripts for kernel and initramfs, if  you
+have also installed another bootloader. With every update of kernel or
+initramfs these hook scripts will be executed and then Lilo rewrite the MBR.
+They don't check whether another bootloader is activated. 
+
+Grub and Grub2 have its own hook scripts which will be executed, too, but
+don't rewrite the MBR every time. If you have installed and configured 
+other bootloader, then be aware, that they work differently and have its
+own hook scripts, which could give you accidental situations. Please read
+the package information about other installed bootloader for correct
+configuration.
+
+
+** XFS defragmenting /boot **
+
+On the XFS filesystem (or others too?), there could growing problems with
+kernel files (vmlinuz*) in /boot directory while someone defragmenting
+partitions. To protect vmlinuz* files from moving to other addresses on the
+disk, which would lead to an unbootable system, it is recommended to use
+'chattr' if the /boot directory have a XFS filesystem.
+
+Lilo 24.1 comes with some hook scripts for this case. Go into directory
+/usr/lib/lilo/hook and start the Makefile as root with 'make install'. Then
+these scripts will ensure that lilo survives when xfs defragments files.
