Sysroot is now created with fakeroot. This allows root access to be only needed for disk image creation, since it uses loopback devices.

 If you feel like ```./script/build.sh``` is too verbose, there exists a symlink _bos_ in this projects root directory. All build commands can be used with ```./bos args...``` instead.

 I have also created shell completion script for zsh. You can either copy the file in _script/shell-completion/zsh/\_bos_ to _/usr/share/zsh/site-functions/_ or add the _script/shell-completion/zsh_ to your fpath in _.zshrc_.
