it's not a hybrid kernel. it is just a file server kernel. of course the same c library and whatnot are used. so there are shared bits, but not many. it is a one-off thing. i also run the same fileserver at home. the source is on sources as contrib quanstro/fs. i don't think anybody else runs it. > Also, about the coraid AoE unit: am I correct in assuming that it does > some sort of RAID functionality, and then presents the resulting > device(s) as an AoE device (and nothing more)? exactly. > Also, another probably dumb question: did the the fileserver machine use > the AoE device as a kenfs volume or a fossil(+venti)? s/did/does/. the fileserver is running today. the fileserver provides the network with regular 9p fileserver with three attach points (main, dump, other) accessable via il/ip. from a client's view of the 9p messages, fossil, fossil+venti and ken's fs would be difficult to distinguish. - erik
