Hey there,

[PATCH 1/2] clients/android: don't override USER in build.sh Export this patch

USER is a standard global environment variable that contains the name
of the current user.  Previously, build.sh would reassign user to be
the id of the current user.  This would break podman, which uses $USER
to find the name of the user to look up in /etc/subuid.

Since environment variables are conventionally upper case, using
lowercase variable names in scripts avoids the problem of overriding
variables in the environment.

This should have been changed too, but I'm not sure what these
instructions are actually for.  I think the idea is that
.build_nested.sh uses them, but looking at the source for that, it
actually uses positional arguments instead.

So I'm not really sure what to do with this until that's clarified.

-    docker run --rm -it -v $BASEDIR/../../:/qaul.net qaulnet/android-build-env /bin/bash
+    docker run --rm -it -v $basedir/../../:/qaul.net qaulnet/android-build-env /bin/bash
   
 else
     echo "Running one-shot-build"
-    docker run --rm -it -v $BASEDIR/../../:/qaul.net qaulnet/android-build-env \
-           /qaul.net/clients/android/.build_nested.sh $USER $GROUP
+    docker run --rm -it -v $basedir/../../:/qaul.net qaulnet/android-build-env \
+           /qaul.net/clients/android/.build_nested.sh $user $group
 fi

[PATCH 2/2] clients/android: fix build.sh undefined variable Export this patch

If no argument was given, this script would produce the error:

    ./build.sh: line 9: [: =: unary operator expected

This happened because the expansion of the [ command became

    [ = "dev" ]

Adding the quotes around $1 makes the expansion

    [ "" = "dev" ]

Which is what we actually want.
