Public bug reported:

Binary package hint: grub

This is ubuntu 9.10 beta5 dist-upgraded, on a MacBookPro dual booting
with macosx 10.6.

I am observing a strange pattern.

First I resized macosx 10.6 partition to leave space for ubuntu.
Then rebooted and installed rEFIT.
Then rebooted and installed ubuntu from a CD (holding down c key to boot from 
CD).
My partition table is as follows:

196 mb rEFIT
25 Gb MacOSX
5 Gb FAT32 (my '/shelf' partition to exchange data from mac to ubuntu and back)
10 Gb ext4  (my root '/' ubuntu partition)
8 Gb linux-swap 
10 Gb ext4 (my '/other' reserve partition)
190 Gb ext4 (my '/home' partition)

The MBR was installed on sd4, my root partition.

After installation, ubuntu wouldn't boot from "Legacy partition 4", as
rEFIT boot menu titles it.

So I rebooted from the installation CD, opened GParted and realized my root 
partition was not labeled as "boot"-able.
I added the "boot" flag to my root partition and rebooted: all ok!

Rebooting any time worked.

Then I run a dist-upgrade that updated the linux kernel and run, as part
of the update process, the grub updater. The latter complained about not
being able to update this type of partition or setup (I can't remember
correctly) but stated it as a warning, and finished without error.

After rebooting, I coudn't boot into ubuntu from rEFIT. I tried several
times.

So I rebooted from the CD, opened GParted, set the boot flag again --
didn't do anything, since it was already there. Closed and rebooted, and
voila, now I could boot again from rEFIT.

So: there is some magic touch missing from the installation of a new kernel. 
Either at grub or elsewhere.
I have seen the phenomenum two times already.

Thanks for looking into this.
