From a quick read, this looks like an application server (ie, all nodes
do is get an exported display, and the bin runs on a central server).
What I want is NFS root (there's a howto on it, but my question was more on
how to get the base OS installed), since I want to have each diskless machine
I serve NFS root to about 80 netbooting NCs running Linux. They also use
Debian for their exported roots. What you mention as a problem for getting
a base install to the machines is something I encountered before.
1) Use of tar has been less than effective when copying over all of the
base files
I'm looking at some Perl code (not mine) that does this
(simplified for clarity):
open(INFILE, $filename);
flock INFILE, LOCK_EX;
open(OUTFILE, $tempname);
flock OUTFILE, LOCK_EX;
...
(read from INFILE, change stuff, write to OUTFILE)
...
rename $tempname, $filename;

Thanks Jeff, that helps. But in this case the rename deletes
a file (with the same name) that's still open (and locked),
and so the inode is going away, right?
I suppose the OS doesn't care since it was opened read-only,
but it sure feels cheesy to me.

No, deletion does not trigger removal of the inode directly. Only the
