FUSE

I find FUSE with sshfs (and ftpfs via lufs emulation) a tremendously useful tool for working on files on a remote machine. Currently knoppix (3.9) cannot compile the FUSE kernel module because the kernel sources aren't present. It'd be nice if this module and libraries were included even without any of the userspace programs if they could be compiled manually.

Your suggestion inclusion of kernel sources and/or FUSE itself has merit. Practically all of us here are not Knoppix developers or Knoppix beta-testers but are just community volunteers. You can contact the developers at their mailing list at http://sympa.linuxtag.net/wws.
