Comment 1 for bug 2028564

We previously encountered this kind of problem when the metadata_csum feature was added in e2fsprogs.

I think we could disable the orphan_file feature the same way, as long as we use the "-0 ^orphan_file" syntax (and not using a "-") to make sure we prevent a regression on this bug https://bugs.launchpad.net/snappy/+bug/1878374.

I will draft a PR to snapd (because now snapd is providing the package to deal with filesystems generation).
