Binary package hint: grub2
I just installed natty alpha 3 on a samsung NC10 netbook. When booting, immediately after the grub screen I see the error message:
'sparse file not allowed.
press any key to continue'
after pressing any key the boot continues as normal.
This is with btrfs on / and a separate ext4 partition for /home. I had created the btrfs partition manually (i.e. in a shell outside ubiquity) simply running mkfs.btrfs /dev/sda1 and it was not reformatted in ubiquity.
