root - Best way elevate the privileges programmatically under different versions of Linux?

Question

There is a standard way (working across Linux distributions) to launch a process (from another application) asking for the root password in order to elevate privileges?

I tried to use gksudo (it is installed in ubuntu by default), but under other distributions (or under other desktop manager) it may not be installed.

Answer 1

I would recommend looking at PolicyKit which is what most modern distros are using to accomplish this.
