If you mount /usr read-only, but want to be able to write to some of the subdirectories of /usr, you can re-mount them on top of themselves, read-write. i.e.: ballast:/up/3.2bin on /usr type nfs (ro,noquota) ballast:/usr/unimacs on /usr/unimacs type nfs (rw,noquota) ballast:/usr/NeWS on /usr/NeWS type nfs (rw,noquota) There is a symbolic link on ballast so that /usr points to /up/3.2bin, so /usr/unimacs and /usr/NeWS are the same directories as usual, but I can write to them from the nfs client. -Don
