One of the things we try to keep in mind when developing AROS is that we don’t want to enforce any particular way of doing things. How a system is configured, what it looks like, or how minimal or feature-rich it is should ultimately be up to the user — or the distribution maintainers. The nightly builds are really just configured with some basic, sensible defaults, primarily so that the people working on AROS have something usable for testing. They’re not intended to show off what AROS can look like, nor are they meant to represent the minimum configuration it can run with. Those are things that distributions and users can decide for themselves. We also try to stay as compatible with AmigaOS as makes sense, particularly where existing software and conventions benefit from it. But m68k isn’t AROS’s primary target, so there will always be some differences and areas where strict compatibility isn’t practical or necessarily the right goal.
