Quick guide to muformat. Create a file s:muformat.allow Each line should consist of the device name of all devices for which formatting is allowed. eg df0: df1: pc0: pc1: rad: Set the following permissions s:muformat.allow rwed group=r other=r sys:system/format rwed group=r other=r c:muformat urwed group=re other=re format, muformat can be anywhere you want, as long as they're in your path. Of course it only works from a shell. Sorry folks but I don't know how to read args from the Workbench. If someone else is interested please do it. Copyright/Disclaimer etc... See the GNU license.
