Bug Description

Binary package hint: os-prober

In testing Ubuntu-11.04-beta1 (Natty), I configured a 3 GB partition (sda1) as btrfs. This can boot with minor adjustments (resolved already in current beta/daily). The default Ubuntu install creates two subvolumes, "@" and "@home" when using a single file system. os-prober in Ubuntu-11.04-beta2 does not detect this install. /etc/lsb-release is present in the "@" subvolume.

I think this should be fixed in an SRU, at this point. I'll add a release-notes task.

This fix allows my sub-volume to be detected.

The suggestion in bug 776850 is incorrect, I'm afraid (and in any case is unrelated to the behaviour of os-prober). I've left more detailed feedback there.

Five months on, I don't think this is in progress; setting back to triaged.
