2019-05-05rdsquashfs: reorder unpack flags, add flag to produce listingDavid Oberhollenzer
The listing command has been used successfully to do the following: - generate a prestine file system using gensquashfs - repeate multiple times: - generate a listing from the file system - unpack only the regular files from the file system - generate a new file system from the listing - run `diff` on the old and new filesystem and admire that they are identical - replace the old file system with the new one, since they are identical Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>

2019-05-04Rename tools to not collide with squashfs-toolsDavid Oberhollenzer
This commit changes the names of the tools to gensquashfs and rdsquashfs so they don't collide with the names used by the squashfs-tools package and the two can be installed side by side. Signed-off-by: David Oberhollenzer <david.oberhollenzer@sigma-star.at>
