Comment 23 for bug 1320402

I'm also have bumped to "imsm raid always resync after boot" issue under Ubuntu 16.04.lts.
I can see that the mdadm-waitidle scrip really does present into the /etc/init.d/ but at the same time no any symbolic links to this script into the etc/rcX.d dirs. I.e. by default this script never executes. I have tried to restore Kxxmdadm-waitidle symlinks into the etc/rc0.d etc the but cannot say yet does this way help or not, my raid is resyncing currently.
