I merge it because it still works for me on a SLE12-SP1 system
with its default btrfs structure.

A few days ago I had learned about a nice (or scaring?)
GitHub function that one can edit files directly via the
GitHub web interface (provided one has write permissions).

Because I only liked to enhance a comment
in 23_filesystem_layout.sh that is output
to disklayout.conf in 23_filesystem_layout.sh
from

echo "# Attributes cannot be determined because no executable 'lsattr' and/or 'findmnt' command(s) found."

to

 echo "# Attributes cannot be determined because no executable 'lsattr' and/or 'findmnt' command(s) found that supports 'FSROOT'."

I dared to do that trivial change directly via the GitHub web interface.

I am impressed how well this is implemented in GitHub.
My direct edit resulted an additional nice git commit
b22ee01
on top of rear master.
