Hi Greg, Thanks for the pointer to this work. It sounds like the FUSE code in FreeBSD and NetBSD have diverged significantly. Does anyone know what originally drove NetBSD in the direction of this “puffs” reimplementation? I’m not saying the FUSE code is awesome and in need of defending, I’m just trying to understand the rationale behind “reFUSING” it. :) If it’s also demonstrably and clearly better, we should probably make this a target for merging between the *BSDs since we have a growing number of foreign-filesystem import and now gluster targets that use it.
