There will be no repacker/resizer or any other modules for the fs until it gets merged into the kernel. During the process of getting reiser4 into mainline many things about the implementation are changing so it is probably impossible to write the compression or encryption modules until it gets merged.
I don't consider it a lacking feature, just a nice checkbox to be able to check. If we get transparent compression in the filesystems (that you can toggle on and off) then that will be great news to marketers. It also could be good news to embedded people if the compression isn't too processor intensive. -- Zac Slade [EMAIL PROTECTED] ICQ:1415282 YM:krakrjak AIM:ttyp99 -- gentoo-user@gentoo.org mailing list
