Well, I guess that's the default configuration. *I* didn't tell it
anything. :-) Remember, I started this with, "I've used lilo all my
life and know it backwards and forwards and sideways and so on, and now
I'm stuck with grub which I don't understand at all." lol
So then, the question becomes: Is there a configuration option
somewhere that I can use to tell this os-prober thing to *not* probe
down a particular directory? I've seen references to being able to just
uninstall it, but I'd prefer to not do that if possible - if I do at
some point add another OS (though it's doubtful - this machine is run as
a server so I can't see a reason why I'd ever do that, but I like to
keep my options open when I can), it would be nice to have this thing
find it. But I'm never going to want to boot to/from the partition
where /backup is mounted, so if there's some kind of "exclude" option,
that would be awesome. Failing that, I'll just put up with the extra
option on the boot menu. It's not like I boot very often... :-)
