1) Do you know if avira will come out with an antivir that works with 
dazukofs?

2) SuSE has a dazuko .src.rpm based on redirfs-0.2 and dazuko 2.3.4.4 
(presumably 2.3.5-pre1, to support redirfs), hence it's a little out of date, 
plus building it against the current 2.6.25.16 kernel works, but the modules 
don't load, with unknown symbol errors. The .src.rpm was originally designed 
against 2.6.25.5.

3) Building the tarballs for dazuko 2.3.6-pre2 and redirfs-0.3 works, and the 
modules load, but antivir complains "antivir[29092]: Error: Unable to setup 
Dazuko parameters" - I get the feeling it can't talk to /dev/dazuko, which has 
major 250.

4) I can't get any version of nullfs to compile on openSuSE 11.0. Have you 
tried that combination? The error for nullfs 0.0.1 is simpler than later 
versions. 0.0.2-0.0.4 errors look similar to:
