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.

Interesting. "udisks/udisks2" is not installed, but "pmount".
Mounting removable devices without "pmount" fails. I also have no networkmanager
running (just plain dhcp on eth0). Sounds good to me :-)
On FreeBSD it looks like the TDEs hal-component does not work propperly when hal is
compiled without consolekit/policykit: it just shows the interlan hd, but no removeable
media - devd based automount still works propperly.

Consolekit was also needed for tdm to implement mulit-seat. I do not know the
current state of systemd inheriting the multi-seat functionality from
consolekit, but when I was building TDE for Arch, when arch dropped consolekit
and went to pure systemd, it broke tdm and there was a big push to implement
multi-seat without consolekit that was never quite brought to fruition.
Slavek probably recalls that mess. A good introduction of the
consolekit/polkit/udisk relationship is:
