Mike Machuidel posted a modified FUSE package to the list back on 
2007/5/27 for shared, writable mmap support, based on Miklos Szeredi's 
series of patches at http://lkml.org/lkml/2007/2/27/293.  Unfortunately, 
the URL Mike posted is no longer available.  Does anyone have the patches, 
or has anyone successfully done the same thing? The Miklos patches make 
changes to the kernel as well as FUSE, which I'd really like to avoid, if 
possible (somehow, Mike succeeded in using his stock Ubuntu Feisty 

The Miklos patches have since been integrated into the 2.6.26 kernel, but 
I can't currently use that with OpenVZ (and I'd much prefer to stick with 
my distribution kernel, anyway).  With an Ubuntu VM running on top of a 
GlusterFS in OpenVZ, I presently run into the same problem Mike did, which 
is that apt-get fails, due to the lack of shared, writable mmap support in 
FUSE.  He got it working, though, whereas I'm going through torture trying 
to get a subset of the 22 Miklos patches to work...
