I actually mount root fs by UUID (UUID=xxxxxxx-xxxxx-xxxxxx in fstab).
May be I lied a little bit with "Mounting /dev/sda1..." message as I
just typed it as I remembered it because there was no chance to copy
and paste it.

I did it by "dpkg-reconfigure linux-image-xxx"

I only use multipath device for backup storage on this backup server
so there is actually no need to mount it at the boot level. I'm gonna
stay with rc.local mounting as it is just enough for me. May be I will
face this problem once again when I need multipath device during boot.
Thank you for your suggestions!
