Probably /net and /host are also psuedo file systems, but I have never seen them before. If they are legit, they are for something I do not run. > The machine is a simple web server and print server with little else on > it. Can some explain to me (or point me to) an explanation of mount > points? A mount point is just a directory where the system attaches pointers to some type of data structure. You create a mountpoint using the mkdir command just like with a directory. It only becomes a mountpoint when something is attached to it - a file system or some other system structure. Of course, actual file systems such as for / or /usr or /home are the most common seen, others, including memory file systems can be created and attached to a directory. When a filesystem is mounted over a directory, if there is something else in the directory - other files and directories - they are covered up until the attached item is unmounted. That all probably isn't very clear, but it should at least let you not worry too much. ////jerry > Thanks, > Graham/ > > -- > > Graham North > Vancouver BC > Canada > > www.soleado.ca > > Kindness is infectous, try it. > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
