there's one major bug in it that I know of, which I reported and fixed in my 
private tree. (and reported the fix)  besides that I've spent many hours 
running with it, w/o experiencing a problem.

Please try w/ the patch I made against 1.1.3 if the cvs version are giving you 
trouble.  I should create a patch of my fix after I wake up for real in a few 
hours.

Subject: [Unionfs] UNIONFS_MMAP unstable

Hi,

 We have done very little testing on it; it's highly experimental, but looks

 available for people to try, and hopefully help us enhance and fix it (while
 we're continuing to stabilize the rest of the code in preparation for a
 first release).
 
 So, consider this a request for testing from those of you who feel
 comfortable enough with the unionfs code, to try out UNIONFS_MMAP, find
 what's missing/broken, and give us feedback (or patches :-)

Well, after using the current snapshot from 3.5.06 on Knoppix with
-DUNIONFS_MMAP, Kernel 2.6.17-rc3-git17, I have to report that this is one of 
the more unstable versions. I get various kernel oopses because of apparently 
defective page caches after dpkg -i (too many different dmesg's to report 
something reliable). Seems t be caused by mmap, but I'll have to retry without 
-DUNIONFS_MMAP again today.

Also, the current snapshot doesn't compile with Kernel 2.6.17-rc3-git17 because 
of wrong calling of sync_page(). It should probably be
block_sync_page(), but that's just a guess.

Btw, is anybody doing something about the "mv directory .." bug?

With kind regards
