Re: copying files back to the server

[Chip Seraphine]

I have a /var/cfengine/hostlib directory on each host, and files the 
server needs to know about get copied over to that directory.  The 
server periodically iterates thru the client list syncing that directory 
to a 'master hostlib' area (on the server).    This requires me to 
autogenerate a 'cf.hostlibs' file that does the syncing on the server.  
(If  that worries you, just iterate across a list using shellcommands 
and rsync.)

If you are lucky enough to be able to get away with it, using NFS is an 
easy way to go.  Assign each host a writable directory on the NFS server 
and have them dump things the server needs to know into that directory.
