Recently there was a post on the Minix 3 google group about porting the BFS filesystem to Minix. The issue came up: are there already BFS drivers for Linux or Windows that might serve as a model to those who intend to do the porting to Minix? I seem to remember that the Linux driver (e.g. on Zeven OS) is read-only. Is there also a fully functional (read-and-write, etc.) driver somewhere, for whatever system? Does anyone have some precise information about it? Also, apart from Dominic Giampaolo's pdf ebook, is there any other source of technical documentation available?
