A harder problem is probably to determine when a file stems from an
encrypted file system / block device. Am almost certain we need kernel
support for that. Storing thumbnails per mount was merely a suggestion;
an easier solution would simply be to not store Thumbnails for files
originating from encrypted file systems / block device.
However, I think the spec does need to mention files originating from
encrypted file systems / block devices. Do you disagree?
