Polkit1

[Dario Freddi]

Just to add my experience as well. What I'm telling you is happening with 
latest polkit trunk configured with:

./configure       --prefix=/usr       --sysconfdir=/etc       --
libexecdir=/usr/lib/PolicyKit1       --localstatedir=/var       --disable-
static       --with-os-type=archlinux

And installed with make install and nothing else. Clean, plain installation.

Let's go:

drf at drfarch:~$ gdb pkexec

This GDB was configured as "i686-pc-linux-gnu"...
(gdb) r nano
Starting program: /usr/bin/pkexec nano
pkexec must be setuid root

Program exited with code 0177.

But...

-rwsr-xr-x 1 root root 22995 13 lug 23:15 /usr/bin/pkexec

pkexec is setuid root. Starting polkitd-1 instead results in:

drf at drfarch:~$ sudo /usr/lib/PolicyKit1/polkitd-1
Registering null backend at priority 0
Using authority class PolkitBackendNullAuthority

(process:31215): GLib-GObject-WARNING **: invalid (NULL) pointer instance

assertion `G_TYPE_CHECK_INSTANCE (instance)' failed

Error registering authority: Could not become primary name owner for

Obviously the policy file is present and should work out. And why nullbackend 
is loaded? Configure said I was using PAM actually. I installed also polkit-
gnome-1, and:

drf at drfarch:~$ sudo /usr/lib/PolicyKit1/polkit-gnome-authentication-agent-1

Enough, I'd say ;) But I'm here, shall you need some more infos.
