Greeting. This is a Request For Comments....

Good morning!

[...]

I'm also wondering if I should include a udev 'rules' file for md in the mdadm distribution. Obviously it would be no more than a recommendation, but it might give me a voice in guiding how udev interacted with mdadm.

I would really like to have a clear separation of competencies. Ideally, mdadm never creates any devices but leaves it all to udev, and all configuration about alternate names ("symlinks") is done in the udev rules file.

I know mdadm needs the devices for the ioctls(). However, much of what it does with ioctl should already be possible with /sys. Thus, in my ideal world, I imagine mdadm to be a manipulator of /sys, instructing the kernel to do stuff with components and arrays, and have udev create and remove corresponding devices in response to kernel events.

I realise this would require a revamp of mdadm, and might actually be better done in a new software designed to eventually replace mdadm. But is this a way forward with which you could befriend yourself?
