Issue

Freshly downloaded Miniforge. Found on regular machine, but easily reproducible in docker:

FROM ubuntu:latest
RUN apt-get update && apt-get install -y wget
RUN wget https://github.com/conda-forge/miniforge/releases/download/23.11.0-0/Mambaforge-23.11.0-0-Linux-x86_64.sh \
    && chmod +x Mambaforge-23.11.0-0-Linux-x86_64.sh \
    && touch $HOME/micromamba \
    && ./Mambaforge-23.11.0-0-Linux-x86_64.sh -p /opt/mamba -b

Gives:

PREFIX=/opt/mamba

I've removed it so my install can continue, but this surprised me.

hmm curious. lets see if updating micromamba fixes things;

once those builds pass, i'll try to add the reproducer to our tests. Seems like a really strange behavior.

We might need to set MAMBA_ROOT_PREFIX in constructor as a workaround.
