openSUSE 13.2 RC2 - Possible to have unified /boot formatted BtrFS?

[rahim123]

Hi,

Is it possible to install the new openSUSE 13.2 RC2 on a single BtrFS formatted / partition, including /boot?

Thanks!

Mostly yes, but grub2-reboot won’t work (i.e. setting for boot once won’t be removed during next boot).

Thanks for the quick reply! Initially I couldn’t get it to work. But for the record, my issue was that I was trying to boot from the MBR instead of the root partition. Works now when configured only to boot from the root partition.

It should work just fine actually; the only possible problem is not enough space to install bootloader after MBR - this can happen with legacy disk partitioning which left only 63 sectors before the first partition and btrfs module is rather big (quick test gives 40K of core.img with btrfs).

Yes, absolutly.
I have the /boot folder within BTRFS root subvolume (even with compression) and it is work well.
Grub2 in MBR of this disk.

I will have to try this at work tomorrow.
