 		DwarFS is a read-only file system with a focus on achieving very high compression ratios in particular for very redundant data.
 		This probably doesn't sound very exciting, because if it's redundant, it should compress well. However, I found that other read-only, compressed file systems don't do a very good job at making use of this redundancy. See here for a comparison with other compressed file systems.
