[torqueusers] Dependencies being ignored from some submit hosts.

Perfect! So hostA runs dnsmasq which builds it's DNS data from
/etc/hosts. In that file I have:

192.168.0.1  hostA hostA.hpc.usu.edu

so getent hosts 192.168.0.1 on hostA returns

192.168.0.1  hostA hostA.hpc.usu.edu

But submitA didn't have that entry in /etc/hosts and gets the DNS view,

192.168.0.1    hostA.hpc.usu.edu.

Adding an entry to /etc/hosts on submitA has fixed the problem.

Thanks for your help,

jbh
