# 1. Disable space check in pacman. This is necessary since the free disk space
#    might not reported properly inside the container. In that case, pacman
#    could stop with an error (see https://github.com/docker/for-mac/issues/5433)
# 2. Install required software (clang is only required because of this
#    workaround: https://github.com/archlinux/alpm.rs/issues/35) and clean
#    package cache afterwards
# 3. Set up rust
# 4. Build repman

# 1. Switch off debug option in makepkg.conf since this leads to building
#    ...-debug packages (which is not wanted)
# 2. Disable space check in pacman. This is necessary since the free disk space
#    might not reported properly inside the container. In that case, pacman
#    could stop with an error (see https://github.com/docker/for-mac/issues/5433)
# 3. Install dependencies and clean package cache afterwards
# 4. Configure sudo (sudo is required by the scripts that repman is calling)
# 5. Create user to execute repman (repman cannot be executed as root since it
#    ultimately calls makepkg which cannot be executed as root)
