So i can confirm it is in fact dagman that's the difference.  if i
take a simple job and do a condor_submit, the output/error files get
created with the correct permissions 0640, if i then submit the exact
same job wrapped in a dag, the files get created with 0644

would it be fair to assume that dagman is launching these jobs as the
user, but it's not pulling the umask from the user, but that of the
condor daemon?
