Suppose I construct a /home partition on a host in the following way: mkdir /home mount /dev/wd0c /home mount /dev/sd0f /homea mount /dev/sd1f /homeb mount /dev/sd2f /homec mount_null /homea/robert /home/robert mount_null /homea/simon /home/simon mount_null /homeb/lucy /home/lucy mount_null /homeb/cvs /home/cvs mount_null /homec/george /home/george mount_null /homec/sam /home/sam So I have a nice consistent /home set up on this machine -- all users home directories appear as /home/whatever, but they are on different partitions to deal with real-world hardware. I would like to be able to export this arrangement to other machines -- is there a way to do this using: 1. Unmodified nfsd/mountd under FreeBSD, on the server, such that a client just mounts server:/home and gets access to all the directories. 2. A way to do this using trivially or mildly modified nfsd/mountd under FreeBSD on the server, such that the client sees server:/home and gets access to all the directories. Or do I have to mount /home, /homea, /homeb, /homec on each client, and construct the nullfs hierarchy on each? Also, with regard to file system quotas -- does a nullfs mount use the quota system from the source of the mount? e.g., will user robert be restricted by the quota arrangement on /homea, where his home directory is found, or because it counts as a different mountpoint, will he be quota-free?
