Comment 10 for bug 1608495

I saw this fix & installed it before your update went out. I did it by hand, so I didn't know about the dracut-core package or enabling/starting the mdadm-shutdown.service. Even without dracut-core, it worked for me.

I did make some changes to 64-md-raid-assembly.rules. I commented out the ENV{ANACONDA}=="?*", GOTO="md_inc_end" line, because I didn't think this applied to Ubuntu. I also made the following change:

ACTION=="add|change", IMPORT{program}="/sbin/mdadm --incremental --export $devnode --offroot $env{DEVLINKS}"

I saw this was updated on the linux-raid list:
[PATCH 2/4] Use correct syntax for passing DEVLINKS to mdadm from udev

I also did 2 reboots & everything seems to be working correctly. One question: Does this mean that Ubuntu 18.04 will use mdadm by default during installation instead of dmraid?
