Looks like the file is now /etc/nfs.conf. Furthermore, the file looks to be INI format compared to arg=value format.

@robnagler the INI format is less amenable to our current perl substitution.

Currently we set the number of threads for the nfs_server with a perl substitution. But, the new INI format has multiple threads= assignments. We only want to edit the one under the [nfsd] block

# debug="all|auth|call|general|parse"
# manage-gids=n
# descriptors=0
# port=0
# threads=1
# reverse-lookup=n
# state-directory-path=/var/lib/nfs

# cache-use-ipaddr=n
# ttl=1800

Any advice on a solution? Pull /etc/nfs.conf into rsconf and write the whole file?

[e-carlin]

We decided we will pull this file into rsconf as a jinja template and update it that way.

We'll likely need a way for rsconf to know what host is being configured because we want to run centos and alma simultaneously. It should be configurable on a per host basis at the python level (not yaml/fconf).

For now punting on solving because this isn't needed for a basic end to end.
