I'll be sure to do that, I come from the open source gpl'ed world.
Its very nice to know when all that time and effort you put into
making a really good piece of software either blows up or works like a
charm :)

Oooo, installing a nice udev rules file might be appropriate for
setting permissions and such for this. However, it seems the kernel
module doesn't actually try and create the device... pvfs2-client
creates the device... is there any reason why the kernel module for
2.6 doesn't try to request that the device be created?
