Hi, Sorry for taking 5 days to respond :/ Since there's already a BFS FUSE implementation on Linux, I'm spending time with the Haiku filesystem API instead. I have UserlandFS up and running. I wrote a tiny add-on that merely logs things to a plain text file. I've also been reading about ZFS. Specifically, a set of ZFS slides[1], the ZFS source code tour[2], the ZFS porting guide[3] and a paper on how ZFS was ported to FreeBSD[4]. I'm also trying to get familiar with the ZFS sources. I now have a rough idea of what porting ZFS will entail. I might have an initial proposal ready by tomorrow. Also, as a pre-GSoC thing, I want to write a file system that mounts ZIP files. I have some rudimentary code ready. I have a question, though: does an add-on like this already exist? And finally, I've been wondering: if my project is picked, who will be the mentor? Ingo? Thanks!
