Proper method of updating DRBL templates?

[McEnroe, Michael]

I'm getting confused as to how system updates are made to carry over into DRBL's image for clients.

I used drblpush -c /etc/drbl/drblpush.conf for a while, but this whacks my nsswitch.conf file (with LDAP config) for the clients every time.  This also seems to restart NFS, hanging all active clients.

I tried using drbl-gen-ssi-files, but this only catches stuff I manually update in /tftpboot/nodes/x.x.x.x/

This came to a head when I upgraded Firefox on the host machine (Kubuntu Hardy).  A vital config file that was added to /etc, as well as dpkg updates (in /var/lib/dpkg/), was not carrying over, causing a headache trying to track down the reason Firefox wouldn't launch anymore.  While I was able to fix it manually, this is generating more overhead than should be necessary.

Is there some simpler, more effective method to updating the node_root when I do package updates on the host itself?

Not really. "drblpush -c /etc/drbl/drblpush.conf" is the easiest one.
However, it does has the problem you mentioned. This is the limitation
of DRBL SSI mode. Since the template tarball is extracted when a client
boots, and the files of /etc/ and /var was extracted into it's RAM.

Steven.
