Comment 8 for bug 259145

I understand the md device dependencies are not available in fstab, I am not sure though what should prevent going through the filesystems and identifying their dependencies in the running system?

In the suggestion the fstab gets merely used as a starting point, a list of filesystems that get set up on boot. And prior to rebooting a list/tree is derived from it, that contains the md devices required to boot and to set up all filesystems mentioned in the fstab.
