That's an interesting article. So aparently consolekit/polkit/udisk and desendents are still around to solve a the multiseat "problem" which died when? 1995? Am I missing some bigger picture here?

Somehow the documentation of consolekit makes me smile in that context: https://www.freedesktop.org/software/ConsoleKit/doc/ConsoleKit.html "Defining the Problem ... To be written."

Polkit documentation is no better, 2. paragraph under "Usage in unprivileged programs"
https://www.freedesktop.org/software/polkit/docs/latest/polkit-apps.html - translates to "avoid polkit" to me.

Ok, as I mentioned before, on devuan nothing changes after I got rid of consolekit/polkit/elogind.

On FreeBSD things are a bit different: I compiled sysutils/hal without consolekit2 and without polkit. I removed consolekit2 and polkit. After restarting hald, "konqueror media:/" works almost as expected: I get one error message "device busy", reloading shows the content of the media. Unmounting gives an error message, but the device is unmounted correctly (which does not happen with consolekit+polkit). But there is no atempt made to mount the device twice (which was what I wrote about some days ago) which is a big plus for me.
