Dropbox confirmed recently (link) that it will drop support for several Linux filesystems; its client will refuse to sync if an unsupported filesystem is encountered.
This project fixes the filesystem detection in the Linux client to restore the sync capability.
This is an experimental fix, not supported by Dropbox. It might cause data loss.
You assume your own responsibility to configure, build and use this code. If you do not feel comfortable with researching and running those steps yourself, or dealing with any problem you might encounter, please do not use this fix.
