I know. Thank you, I only use label instead of uuid in non raid configuration and even the raid itself is mounted by label. Don't think anyone but you is stupid.

the above *is not* about /dev/by...
it's about the UUID of the 3 RAID devices itself

I don't care I use LABEL myself...

bla, as you can see my mdadm.conf don't contain *any* devices
it don't contain any scan stuff

Fine. Again where is it documented? The documentation the contrary. So go and fix the doc instead of ranting again end user.

but the kernel line contains mentioning the 3 raid-arrays explicit
rd.md.uuid=1d691642:baed26df:1d197496:4fb00ff8
rd.md.uuid=b7475879:c95d9a47:c5043c02:0c5ae720
rd.md.uuid=ea253255:cb915401:f32794ad:ce0fe396
Do not want to do that messing in grub automatic config files...
