SECURITY:
- This is used when users want to install to a different prefix, for
instance to a LTSP image or a virtual machine.
- This could be used to overwrite files not owned by the user using
a carefully created package file.

SECURITY:
- Normal users require admin authentication to enable or disable
software sources as this can be used to enable new updates or
install different versions of software.

SECURITY:
- Normal users do not need authentication to install signed packages
from signed repositories, as this cannot exploit a system.
- Paranoid users (or parents!) can change this to 'auth_admin' or
'auth_admin_keep'.

SECURITY:
- Normal users require admin authentication to install untrusted or
unrecognised packages, as allowing users to do this without a
password would be a massive security hole.
- This is not retained as each package should be authenticated.

SECURITY:
- Normal users do not require admin authentication to refresh the
cache, as this doesn't actually install or remove software.

SECURITY:
- Normal users require admin authentication to rebind a driver
so that it works after we install firmware.
- This should not be set to 'yes' as unprivileged users could then
try to rebind drivers in use, for instance security authentication
devices.

SECURITY:
- Normal users require admin authentication to remove packages as
this can make the system unbootable or stop other applications from
working.
- Be sure to close the tool used to remove the packages after the
admin authentication has been obtained, otherwise packages can still
be removed. If this is not possible, change this authentication to
'auth_admin'.

SECURITY:
- Normal users require admin authentication to rollback system state
as this will change a large number of packages, and could expose the
system to previously patched security vulnerabilities.

SECURITY:
- Normal users do not require admin authentication to set the proxy
used for downloading packages.

SECURITY:
- Normal users require admin authentication to add signing keys.
- This implies adding an explicit trust, and should not be granted
without a secure authentication.
- This is not kept as each package should be authenticated.
