With my ide driver and the md stuff all built into the kernel, my software
raid drives and associated /dev/md? devices are detected and created by the
kernel.
With the md stuff built in but the ide driver modular and loaded later by
udev, the drives are not detected.
So, I guessed that perhaps if I made the md stuff modular aswell and load it
_after_ loading the ide driver, this might kickstart the auto-detect stuff.
But it didn't :(
Is there a way to make auto-detection work without having the ide driver built
in?
TIA

No, they aren't.

No, it wouldn't.

Don't use in-kernel auto-detection. Use mdadm to do the
auto-detection for you.
mdadm --assemble --scan --homehost='<system>' --auto-update-homehost
might work providing your hostname has been set by the time it runs.
