Thanks to Renato Botelho and you = for making clear that I'd read something into the description that just was = not written into the description. For now I've adopted using an explicit env SRCCONF=3D"/dev/null" in the = scripts as the means of avoiding an unexpected contribution and I still have env = SRC_ENV_CONF=3D use for picking out the file: I then do not have to worry about if I = reference any of the special values in the file referenced or not, nor about what /etc/src-env.conf or /etc/src.conf might have in them. I may change this at some point and follow your suggestion to just use = SRCCONF=3D to find the file because as time goes on it looks more like I'm unlikely = to experiment with any "special values" in the files. =3D=3D=3D Mark Millard markmi at dsl-only.net
