Subject: - with mdadm 3.x and udev we don't need mdadm.conf to try to init arrays
X-Git-Url: https://git.tld-linux.org/?p=packages%2Frc-scripts.git;a=commitdiff_plain;h=55195c6f420b28b0bcd54527146ac375797fedb7

- with mdadm 3.x and udev we don't need mdadm.conf to try to init arrays
- try starting raid before trying lvm - lvm on raid is common setup
