Description

I tried running repo2docker as root and got a rather cryptic error message.

 ---> 48ed20783f45
Step 13/32 : RUN adduser --disabled-password     --gecos "Default user"     --uid ${NB_UID}     ${NB_USER}
 ---> Running in 7ece88c37beb
adduser: The user `root' already exists.
Removing intermediate container 7ece88c37beb
The command '/bin/sh -c adduser --disabled-password     --gecos "Default user"     --uid ${NB_UID}     ${NB_USER}' returned a non-zero code: 1(rcs18) root@DrosoNeuro:/home/drosoneuro

Is there any way to tell repo2docker to create a user under a different name?

Contributor guide

Research direction
Investigate how the Dockerfile is generated and add handling for the case when NB USER is root or when running as root, possibly by renaming the user or skipping user creation if already root.
