Makedeb Docker Permissions Error With Noble, Works With Jammy

[dfloer]

I'm working on a build system using the makedeb arm64 docker container (on an arm64 Jammy host) to build versions of a couple packages for Jammy and Noble based systems. Things work great for Jammy, but not for Noble. I get a permissions error: [!] You do not have write permission for the directory $BUILDDIR (/home/makedeb). and note that on Jammy, the /home/makedeb directory is owned by user "ubuntu", but on Jammy it's "makedeb".

Here's a minimal repro:
docker-compose.yaml

services:
  build-jammy:
    volumes:
      - ./build/jammy:/home/makedeb
    build:
      context: .
      dockerfile: Dockerfile-jammy

  build-noble:
    volumes:
      - ./build/noble:/home/makedeb
    build:
      context: .
      dockerfile: Dockerfile-noble

Dockerfile-jammy

FROM ghcr.io/makedeb/makedeb:ubuntu-jammy
CMD pwd; ls -la .; makedeb

Dockerfile-noble

FROM ghcr.io/makedeb/makedeb:ubuntu-noble
CMD pwd; ls -la .; makedeb

I then created a directory structure to test (empty PKGBUILD files are fine for this repro):

mkdir -p build/jammy
mkdir -p build/noble
touch build/jammy/PKGBUILD
touch build/noble/PKGBUILD

And then build and try to run the containers:

docker-compose build
<successful results trimmed>

In my code, I've got PKGBUILDs ported from Arch, but I don't need an actual PKGBUILD to demonstrate the permissions issue, so here's the output from
