/dev/puffs is missing
I decided to experiment with PUFFS and reFUSE
Added kernel option PUFFS and pseudo-device putter as per puffs(3), recompiled kernel. Now I have a /dev/putter device but no /dev/puffs which the manual page says should exist in /dev
Then upon trying to mount an NTFS partition using ntfs-3g /dev/da2s2 /mnt/windows I get a number of errors saying Operation Not Permitted.
This is on current master.
