I have a systemimager server here with a configuration similar this. In this server, I have some file systems to hold images mounted by NFS from a NetApp filer.
This works well, but, sometimes, when I install a machine, strange things happens and I have to do an updateclient on this newly installed system to correct the installation. I think the client are not grabbing all the files from the server. I'm using SystemImager 3.6.3 with rsync. This problem happens only with this SystemImager server. I have others servers, holding the images on local disks and they don't have this problem. I think this is a NFS issue. I'm living with it because I don't have a large disk to hold all the images needed by this server, but I will try to use other transport to install the clients different of rsync.
