Console Lockdown.
...
Allow members of group 'console' to use tty1 to tty7. Everyone else except
members of group 'console-unrestricted' are restricted from using console
using ancient, unpopular login methods such as using /bin/login over networks,
which might be exploitable. (CVE-2001-0797)
Not enabled by default in this package since this package does not know which
users shall be added to group 'console'.
In new Whonix builds, user 'user" will be added to group 'console' and
pam console-lockdown enabled by package anon-base-files.

This is required because otherwise something like "sudo bash" would count as a
