Hey,

Similar to what we do in overlayfs and now in cachefiles too ecryptfs
should rely on a private mount that can't change mount properties
underneath it and puts ecryptfs in full control (apart from changes that
affect the superblock of the underlying fs of course) over the mount it
is using to store its encrypted files in.

Thanks!
Christian
