OK, now I understand ... This can actually be done with existing facilities
in Samba, in a two step process.

In [profiles] you can use environment variables in the path:

    path = /some/path/%$(PROFILE_PATH)

You set up a file in a root exec for the netlogon share, as you are
probably logging on ... and then you use the 'source environment' parameter
before the path parameter in your [profiles] share to read the environment

If you want more info on using environment variables in macros, have a look
at Special Edition, Using Samba.
