- move MINIX3-specific files into minix/lib/libpuffs; - resynchronize the remaining files with NetBSD code; - remove a few unnecessary changes; - put remaining MINIX3-specific changes in __minix blocks; - sort out the source files being linked at all. The result is that libpuffs now successfully links against FUSE file system programs again. It can successfully mount, perform some of the most basic operations, and unmount the file system.
