I've used JFFS2 on uClinux, and found it quite robust wrt blocks with checksum errors. But, yes, JFFS2 isn't designed for disk media. I'm ashamed to admit that sometimes I envy NTFS's transparent file compression. Yes, it's very slow for general use, but it would be ideal for backups, old log files, etc. ext2 has had an unsupported "compressed" attribute for years. Perhaps it's extremely difficult to implement, but a very desiderable feature that Linux still lacks. -- // Bernardo Innocenti - Develer S.r.l., R&D dept. \X/ http://www.develer.com/ -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx http://www.redhat.com/mailman/listinfo/fedora-devel-list
