However, Linux only supports running NFSv3 as a server. what about CONFIG_NFSD_V4 ? that looks like NFSv4 as a server to me ... > While Linux 3.0 still has difficulty accessing NTFS volumes (the > default on modern versions of Windows), support for mounting Windows > network shares has been significantly improved. with ntfs3g (built on FUSE), i dont think this is an accurate statement. even if your focus is purely on in-kernel fs's, this is at least a bit misleading. > In conjunction with an internal sensor, this > feature can mean the difference between a nasty look at a pet or loved > one or a nasty look at a pet or loved one followed by a trip to the i think the first "or" on this last line should be an "and" > devices.
