Question:
I am mounting a filesystem using NFS (from one Sun 4 SPARCstation
to another). I know that if I mount it onto a directory with files in it,
the files become unavailable. Is it a bad idea to do this or not?
Specifically, I want /usr/lib/X11 files to be contained on one machine
(there is a lot of font info that takes up space). But if the server or
network is down, I want the others to be able to startup X (and for that
they need minimal font files, rgb files, ...). I already
have put important executables (X (server), xterm, ...) on each machine,
but have the frills on the server (oclock, xcal, ...).
I have RTFM, but failed to find a mention of "mounting over" files.

Yes, it will work; I have a similar setup for the console terminfo files so that I can use vi in single user mode without having to mount /usr. The only catch is that having any of the files open will block the mount; in your case, the users will have to exit X and be out of the directory before the NFS mount will work. You will, of course, lose the disc space the files occupy. > I have RTFM, but failed to find a mention of "mounting over" files. I've never seen mention of it myself, I sort of stumbled onto it when copying a file into an unmounted structure--it went into the directory, instead, and when the structure was mounted, the file vanished! -- Gary Heston System Mismanager and technoflunky uunet!sci34hub!gary or My opinions, not theirs.
