Because I am using cfengine in an environment where we are in the middle
of a slow rolling transition from one domain to another, I've written a
little script to determine the right domain for each client host at
runtime. The script has been fully tested and works perfectly given two
arguments: the IP address and the hostname. So in update.conf I have:
domain = ( ExecShellResult("/admin/bin/getdomain $(ipaddress)
$(host)") )
But that turns out not to work. cfagent -d -qv shows why, because a
bogus value is being used for $(host):
