Well, they are boot loaders, BOOT_LOADERS ARE DIFFERENT. VERY DIFFERENT. Not shouting, just emphasis. One cannot think of boot-loaders in OS terms, as they are not the OS. lilo does indeed need to be re-written to disk when the partition table changes, it does not have the ability to dynamically read a disk, it has no clue what a file or an fs is. This makes life simple, but you need to remember the extra step. grub does support dynamically reading disks, meaning there's no extra step when making changes. But it did move the complexity into menu.lst. Which one to use? It's a trade-off. Decide for yourselves where you want the complexity to be, and use that one. You will never eliminate the complexity of a boot loader, you can however contain it somewhere YOU are familiar with and where you feel comfortable working with it. -- alan dot mckinnon at gmail dot com
