A while ago I'm experementing with 'IPX network browser' which shows NetWare servers as directories and allows to go down to see volumes, print queues etc. You probably should look at Coda file system. It have a kernel part which interacts with 'Venus' - a user-land daemon. Coda folks done a great job discovering many weird cases in such model. It would be nice if we're have something like 'userfs' (or 'daemonfs') with unified interface and mount command like this: # mount_user /mydaemon /mountpoint so, all that I need to create a new file system is to write 'mydaemon' program. -- Boris Popov http://www.butya.kz/~bp/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
