I don't know what is generating that 'delete as root' entry.
It becomes available when DoAsRoot is installed ..... which gives a service menu open_as_root.desktop with just the one entry 'open_as_root'.
But I get not 'Open As Root' as one might expect, but 'Edit As Root' and 'Delete As Root' as the service menu entries.
In other words ...... I have no idea
Using the ServiceMenuEditor I have read only access to the 'Delete As Root' service menu which has the following commandkdesu "rm -f -r" %U
There are also an 'Open As Root' and 'Edit As Root' service menu entries in the editor.EDIT
sram.d.desktop is the service menu concerned ?
