I didn't succeed in opening gnome-disks as root.
G_IS_DBUS_CONNECTION failed
G_IS_DBUS_PROXY failed
Just a quick recap about this hacked install:
* encrypted internal HDD not recognized as root (same with different file
managers).
* I can input the passphrase as the normal user, but opening is "not
authorized".
* pkexec doesn't work (and when it works on a working machine, the command is
too complex/long)
polkit-agent-helper-1: error response to Policykit daemon: GDBus-Error:

==== AUTHENTICATION FAILED ===
Error executing command as another user: Not authorized
* I tried system updates
* Trying Parabola is a good last resort
