I'm running Whonix 10 under Qubes R3 rc1, and I notice that when I run
"su -" from a terminal, it asks me for a password.  Entering a blank
password yields an incorrect password error, as does entering
"changeme" (which is the default password on Whonix under VirtualBox).

"su -" works fine on my Fedora 21 Qubes VM (doesn't ask for a
password), so I gather that this issue is specific to Whonix under Qubes
.

Is there a preferred method of using su under Qubes-Whonix?  Is this a
known bug/quirk?  Am I doing something obviously stupid?

Thanks.

Hi Jeremy,

Whonix is based on Debian and is configured to use the 'sudo' command
for privileged access. The traditional way to get a root prompt with
sudo is 'sudo -H bash' however I find 'sudo su -' works just as well.
