'lb init' needs root privileges?

[Federico Bruni]

I think that in version 3 I was allowed to run 'lb init' as normal 
user. On version 4 I get this:

$ lb init
E: need root privileges
$ apt-cache policy live-build
live-build:
 Installed: 4.0~alpha37-1
 Candidate: 4.0~alpha37-1
 Version table:
*** 4.0~alpha37-1 0
       900 http://http.debian.net/debian/ unstable/main amd64 Packages
       100 /var/lib/dpkg/status

Maybe the examples in the documentation should be updated?
