Agreed. Also, check the access rights set on the NAS end. I'm no MAC user either but perhaps your upgraded OS is checking acess rights on the NAS that it wasn't checking before.
Well, I'm about to give up. I've gone through every single permission and access rights option on the NAS, no luck. Again, what completely confuses me is that I can run the script manually from the shell and everything works perfectly. So I know that the NFS directory is mounted, and that root user can read the files in it. But as soon as it's a cron job or a launchd job that runs the script it can see the file, but can't read it.

The log simply says:

Code:
cat: /System/Volumes/Data/nfs/hosts: Operation not permitted

Without a doubt the upgrade to Catalina resulted in scripts being run within the context of cron or launchd to use a different environment than that of the command line. This approach of mine works on ALL my other Linux, *nix (SunOS, Solaris, HP-UX, AIX, Linux), heck, even OpenVMS, but no longer on Mac OS X. Grrrrr....

DESCRIPTION

	 xen-create-nfs is a simple script which allows you to easily create
	a single configuration file for a Xen guest which will mount its remote
	filesystem over an NFS root.

	 It doesn't create any images to use for local storage, and it doesn't
	support more than the minimal number of options to completement the
	existing xen-create-image script, however it is hopefully useful.

REFERENCE

	 For more details on what you'll need to support NFS-root Xen guests
