Supporting Fedora Asahi Remix

[peterdavidfagan]

I wish to debug and develop ROS 2 code on my MacbookAir with Fedora Asahi Remix but currently this aarch-based distribution is not recognised by rosdep.

Update: I realise this may be more of a rospkg issue, as os_detect is imported from this package.

I realise this may more of a rospkg issue, as os_detect is imported from this package.

Doing it properly requires both. We want rospkg to know the difference between Fedora and Fedora Asahi Remix, but as it stands right now, we want rosdep to treat both distributions the same since they'll contain the same packages.

In the interim I got things running by editing the release files (super suboptimal but I wanted to see if drivers worked as expected for GPU). Foxglove + mujoco sim works:

Further update: many ROS package dependencies don't seem to have releases for fedora though :(. I also tried Asahi Ubuntu but it only supports 23.10.

For short term workarounds you can use the ROS_OS_OVERRIDE to force the detection or the --os= option.
