1. I am running: Linux server.domain.com 2.4.0-0.43.12smp #1 SMP Wed Dec 27 18:23:19 EST 2000 i686 unknown 2. I upgraded lilo to: # rpm -q lilo lilo-21.4.4-12 3. After rebooting I never get complete boot prompt, it hangs displaying only "LIL 4. Booted with floppy boot disk OK! 5. executed # lilo Added smp240-043.12 * Added lin240-043.12 6. Rebooted OK! I suggest that you modify RPM script to execute lilo automatically after upgrade to rewrite boot record
Unfortunately, it's impossible to definitively tell whether or not grub or lilo is being used as the bootloader so running lilo has a very legitimate possibility of hosing someone's bootloader configuration as well.
