e2dis: a Jigdo-like tool for Ext2+ FS images

[Ivan Shmakov <ivan@gray.siamics.net>]

	BTW, I've just announced [1] the availability of the code which
	(given some attention and care) may be turned into a Jigdo-like
	suite for Ext2+ FS images.

	(The casuality of fragmentation on such filesystems greatly
	reduces the applicability of the FS-agnostic Jigdo tool.)

	Perhaps, this may lessen the burden of the distribution of
	Debian virtualization images.  (Should it become a part of the
	current practice.)

	Alternatively, this tool may allow for “smarter” virtualization
	images' backups.  Or, it may be used to save the bandwidth when
	sending a whole virtualization image, e. g., to demonstrate a
	hard to reproduce bug.
