   https://github.com/apache/superset/commit/d46aa6004d3ee78929048f607e853f7a77237af5#diff-dd2c0eb6ea5cfc6c4bd4eac30934e2d5746747af48fef6da689e85b752f39557 appears to be related. It is a recent commit that references `/app/superset_home` and the commit message is about fixing docker superset permissions.
   
   It looks like that change is counting on `useradd` to create the user's home directory. `useradd` doesn't appear to do this by default, but will with the `--create-home` flag. Additionally, it seems that `useradd` will not create parent directories, meaning that `/app` already has to exist. These steps seem to work and give the desired result.
   
   ```
   $ docker run --rm -it python:3.7.9 bash
   root@2a032833e3c4:/# mkdir /app
   root@2a032833e3c4:/# useradd --user-group -d /app/superset_home --no-log-init --create-home --shell /bin/bash superset
   root@2a032833e3c4:/# ls -l /app
   total 4
   drwxr-xr-x 2 superset superset 4096 May 26 17:14 superset_home
   ```
