Re: [expert] LILO v GrUB

Let me add one more thing about Grub that many people are not aware of. 
 Grub has a shell-like interface which you can bring up when the Grub 
menu appears.  From this shell you can search for kernels on your 
drives, set the root partition and kernel to boot from and then boot 
into you new setup on the fly.  This means that even if you screw up 
that text file, you can still boot into your system without resorting 
to booting from a CD.

I use GrUB because of its simplicity. Configuring means simply

text file. Nothing to run afterwards. This makes chroot on rescue

unnecessary, which makes explaining rescue over the phone or email 
much
easier.
Now that is the first real reason I've heard for the grub advantage 
(the
chroot part.)  hm.

Another capability of grub that, afaik, does not come with lilo is 
command line completion from the grub prompt, allowing you to suss out 
partitions, kernels, etc. on a completely unknown system and boot from a 
grub floppy, e.g:

grub> root (hd  [Tab]
 Possible disks are:  hd0 hd1 hd2 hd3
grub> root (hd3,  [Tab]
 Possible partitions are:
   Partition num: 0,  Filesystem type is reiserfs, partition type 0x83
   Partition num: 4,  Filesystem type is reiserfs, partition type 0x83
   Partition num: 5,  Filesystem type is reiserfs, partition type 0x83
   Partition num: 6,  Filesystem type is reiserfs, partition type 0x83
   Partition num: 7,  Filesystem type is reiserfs, partition type 0x83
   Partition num: 8,  Filesystem type is reiserfs, partition type 0x83
   Partition num: 9,  Filesystem type is reiserfs, partition type 0x83
   Partition num: 10,  Filesystem type is reiserfs, partition type 0x83
grub> root (hd3,7)  [Enter]
Filesystem type is reiserfs, partition type 0x83
grub> kernel (hd3,7)/boot/  [Tab]

You can add kernel commands and boot with boot.

Not a common need but still neat.  More commonly useful is the 
capability to edit from the menu screen, which I have used when a 
partition change or unusable kernel left the system unbootable from the 
old menu.  Tom Berger wrote a page about grub's capabilities here:
