Re: why can't i use grub with an ext3 /boot partition?

possibly related to an earlier post that discussed grub but, when

am not offered the chance to use grub as a bootloader.
as best i can tell, that /boot partition must be both:
1) set as bootable, and
2) ext2 format
otherwise, i'm stuck with lilo. is this true? is there a reason the
debian install can't handle grub and a bootable ext3 partition? i've
tested this a number of times and it seems that ext3 is the deciding
I can't give you the answer, but I can confirm it's possible in sid, at
least by devious means:

This installation is on a brand-new drive and was a fresh Lenny
netinstall followed by a switch of repositories to sid and a dpkg
--get-selections from a file made on my previous machine.
I can't swear that grub was installed at the netinstall stage, though I
thought it was. It's certainly there now, along with its grub2
hitch-hiker, and there's no sign of lilo having existed on this machine.
I'm not about to do the upgrade-from-grub-legacy, as I did that a few
days ago, spent most of a day trying to fix the resulting unbootable
machine and ended up reinstalling the OS. I could find no other means,
using various boot/rescue media followed by chroot, of reinstalling
either grub or grub2.
At least with lilo, you can fix it in ten minutes if it breaks. And most
of that is time spent looking for the boot floppy.
