`init` command only callable through workaround

[svensp]

It is not possible to call init in the contaIner through the recommended commmand docker run -it -v $HOME/.rancherize:/home/rancherize/.rancherize -v /var/run/docker.sock:/var/run/docker.sock -v $(pwd):$(pwd) -w $(pwd) -e "USER_ID=$(id -u)" -e "GROUP_ID=$(id -g)" ipunktbs/rancherize init

Reason: init is installed as a program inside the container and thus the init executable is called instead of the rancherize command.

Calling it causes it very weird output:

can't run '/sbin/openrc': No such file or directory
can't run '/sbin/openrc': No such file or directory
can't run '/sbin/openrc': No such file or directory
can't open /dev/tty1: No such file or directory
can't open /dev/tty2: No such file or directory
can't open /dev/tty3: No such file or directory
can't open /dev/tty4: No such file or directory
can't open /dev/tty5: No such file or directory
can't open /dev/tty6: No such file or directory
can't open /dev/tty1: No such file or directory
can't open /dev/tty2: No such file or directory
can't open /dev/tty3: No such file or directory
can't open /dev/tty4: No such file or directory
can't open /dev/tty5: No such file or directory
can't open /dev/tty6: No such file or directory
can't run '/sbin/openrc': No such file or directory
The system is going down NOW!
Sent SIGTERM to all processes
Sent SIGKILL to all processes
Requesting system reboot

because init tries to take control of the docker container

Expected:
docker run -it -v $HOME/.rancherize:/home/rancherize/.rancherize -v /var/run/docker.sock:/var/run/docker.sock -v $(pwd):$(pwd) -w $(pwd) -e "USER_ID=$(id -u)" -e "GROUP_ID=$(id -g)" ipunktbs/rancherize init calls the init function of rancherize

Workaround:
explizitly calling rancherize init works
docker run -it -v $HOME/.rancherize:/home/rancherize/.rancherize -v /var/run/docker.sock:/var/run/docker.sock -v $(pwd):$(pwd) -w $(pwd) -e "USER_ID=$(id -u)" -e "GROUP_ID=$(id -g)" ipunktbs/rancherize rancherize init
