Boot Loader Detection: GRUB or LILO?



I've had an interruption in my email service and don't have individual
email responses here to which to reply. Fortunately, I can read the
archive and will try to respond here.

It will tell you if grub has been used, not necessarily if it is the
current boot loader. I tried that on my test system and found both the
keywords LILO and GRUB in its MBR (they are in two different places in
the MBR). I have not yet tried re-running lilo on that system to see
if lilo will clobber the GRUB keyword. But I know that grub does not
clobber the LILO keyword.

That would solve it for Fedora, but won't help non-fedora users. Also,
what if the user switches to a different boot loader? The new boot
loader would have to know to over-write bootloader.conf.



Arrgggh. Nothing's perfect; I guess I'm going to have to muck with
it. I'll probably have to warn the readers and suggest they hard code
which one (if any) to use.
