GRUB Legacy.

Debian installer auto-detected my other linux OS (openSUSE 10.3) and
added to "/boot/grub/menu.lst", I had to do nothing :-?

Which seems to be a script/routine that first checks for the availability
of "os-prober". So it makes sense to me that if anyone wanted to use
the"update-grub" and its auto-OS-detecting feature, this package should
be needed/installed.

More than "recommended" it should be "required", provided that "update-
grub" will lack some features if not present :-?

Yes, but any system that you install _after_ Debian will not
automagically show up in the menu. You'll probably have to add it by
hand then.

Exactly.

No, there are people like yours truly who use Debian as their sole
operating system. Others might use some other bootloader in the MBR and
chainload grub, they probably don't need os-prober either.

I just checked again and os-prober is intalled on my system. I am not
sure why I missed this earlier.

Curiously though, update-grub is now detecting Fedora 13! It was not
doing so last night. And my bash history shows that I did not install
os-prober between then and now.

I check my aptitude log and it shows that os-prober was on HOLD three
days ago (I supposed when I did the initial installation). After that
installation, the trunk kernel and grub in Testing were giving problems
so I pulled those from Unstable. Perhaps this messed up os-prober somehow.

Today I was messing around with scim. Last night I did a full-upgrade.
And now I notice that F13 is being detected by update-grub.

I wish I would tell what I changed. So even though the problem is
solved, but I am at a loss to explain what did it.

Boot up Debian, at terminal,
sudo grub-install /dev/sda

Well, I wrote that too soon.

Here is what update-grub puts in /boot/grub
/grub.cfg regarding the Fedora 13 installation:
#######################################################
menuentry "Fedora release 13 (Goddard) (on /dev/mapper/vg1-lv8)" {
insmod part_msdos
insmod ext2
set root='(hd0,msdos5)'
search --no-floppy --fs-uuid --set
b40b5b7f-6999-4a12-9d3b-62e0fc892a40
linux /vmlinuz-2.6.33.6-147.fc13.x86_64 root=/dev/dm-1
}
#######################################################

It is missing the initrd line. Without that line the kernel does not
boot and panics and halts.

I have to put the correct stanza myself in /etc/grub.d/40_custom to get
the correct grub entry which works:
#######################################################
menuentry "Fedora release 13 (on /dev/mapper/vg1-lv8)" {
insmod part_msdos
insmod ext4
set root='(hd0,msdos5)'
search --no-floppy --fs-uuid --set
b40b5b7f-6999-4a12-9d3b-62e0fc892a40
linux /vmlinuz-2.6.33.6-147.fc13.x86_64 root=/dev/mapper/vg1-lv8
ro quiet
initrd /initramfs-2.6.33.6-147.fc13.x86_64.img
boot
}
#######################################################


So there still appears to be some problem somewhere.
