Is it possible to make a dynamically risizing filesystem-as-file?












0















I'd like to do something along the lines of



mkfs -t btrfs filedrive
mount filedrive /media/fuse


Without specifying a particular size, I'd like to be able to have the file grow in size as I write files into the mounted filesystem, and shrink when files are deleted.



Is there some mechanism for this?





I have also seen this question and I am aware that it could in theory be managed manually, but my question has nothing to do with ecryptfs and focuses on the automatic aspect. I do not particularly care about the filesystem type inside the file.
