Public bug reported:
Hi, I tried to install Ubunutu on a multi device Btfs file system. Before
installation I created the Btrfs multi device system with the following command:
```
$ sudo mkfs.btrfs --force --data single --metadata single --label Ubuntu_Btrfs
/dev/sda1 /dev/sdc1
$ sudo btrfs device scan
```
I checked the mount handle to be /dev/sda1 (& not /dev/sdc1) and tried to
install Ubuntu with /dev/sda1 as root `/`. I suppose the error occurs due to
the identical UUIDs of /dev/sda1 and /dev/sdc1 when trying to install the
bootloader - but I don't know.
Motivation for this was possibly another Btrfs-incompatibility: After
installing Ubuntu18.10 on the Btrfs-/dev/sda1 I btrfs-device-added
/dev/sdc1 to /dev/sda1. This caused the boot process and the login
screen to be very 'freezy' having issues to wait for the screen to build
up and the cursor movement and keyboard input to finally display on the
screen...
Thx & Greets!
