I tried to compile unionfs 1.4 adding -DUNIONFS_IMAP in the fistdev.mk file, but 
the unionfs.ko module wouldn't compile. I'm not sure that I'm attempting to 
compile in the correct way, though. Some step by step instructions would be 
welcome. My first concern is just to get the export to mount at all.

As a module.

Thanks, Michael
