The intention is to start UnixAos with a configuration file with a name other than "Configuration.XML".
This name is a CONST in Configuration.Mod, in A2 and not specific to AosUnix.
Another means to achieve this could be to make Configuration.XML a link to my other configuration file.
Rather than tangle with a link I put a cp command in a shell function. A configuration identified by hostname is copied to Configuration.XML before starting AosUnix.
In case anyone is interested, the shell function is listed in
http://carnot.yi.org/ComputerSystems.html#OLPC . Scroll down to my usage notes.
