Arguments for gnutar

[Dirk-Willem van Gulik]

Is there any way one could pass arguments to gtar ?

I.e. along the lines of below ? As to get some level of control over the 
‘STRANGE’ warnings/output ?

Or does this always mean the use of amgtar ?

Dw.

define dumptype root-tar {
...
    program "GNUTAR"
    property "COMMAND-OPTIONS" "--warning" "no-xdev”
...
}
