+# 1. Install just enough for conda to work
+# 2. Keep $HOME clean (no .wget-hsts file), since HSTS isn't useful in this context
+# 3. Install miniforge from GitHub releases
+# 4. Apply some cleanup tips from https://jcrist.github.io/conda-docker-tips.html
+#    Particularly, we remove pyc and a files. The default install has no js, we can skip that
+# 5. Activate base by default when running as any *non-root* user as well
+#    Good security practice requires running most workloads as non-root
+#    This makes sure any non-root users created also have base activated
+#    for their interactive shells.
+# 6. Activate base by default when running as root as well
+#    The root user is already created, so won't pick up changes to /etc/skel
