When btrfs is used to fit more content into the partition, mounting fails because ext4 was hardcoded. When mounting ext4 fails, try mounting as btrfs.

There was a problem hiding this comment.
Looks sane to me but I'd ask someone with some more go experience to look at it.

How to use/testing done
This was built and tested with the coreos-overlay branch
kai/bootengine-verity-hashoffsetfrom flatcar-archive/coreos-overlay#1106 and flatcar-scripts branchkai/btrfs-usr-oemfrom flatcar/scripts#131 in http://jenkins.infra.kinvolk.io:8080/job/os/job/manifest/3029/cldsv/ where the Flatcar image that has a btrfs /usr partition and OEM partition.While the actual switch to a btrfs filesystem on the /usr partition is only possible when all changes are part of a Stable release because update-engine needs to know how to handle the new filesystem when updating, we can already do the switch for the OEM partition.
