The default user in

is for security reasons a non-root user with uid 1000:

$ docker run --rm -ti mambaorg/micromamba:1.4.9-bullseye-slim
(base) mambauser@b82a37bc6fff:/tmp$ id
uid=1000(mambauser) gid=1000(mambauser) groups=1000(mambauser)
(base) mambauser@b82a37bc6fff:/tmp$ 

I forgot this in PR #23 and failed to implement Issue #15, which is causing errors for people who are working at @main and not secure pins (sorry networkx and xarray).

I will need to fix this tomorrow to ensure that things are running in login shells and with proper permissions.
