Jeffrey Hsu might have done it. If not, beware: it did not formerly work. I got it working as part of my mount code changes for integrating root and non-root mount handling, and pushing root vs. inferior mounting up to the common code layer (where it belings). I had to do it for the Win95 version of the VFS framework, since Win95 insists that FS's be mounted each on its own virtual root (one FS, one drive letter). The read-only mount fix was a side-effect of allowing a mount before fsck to get the drive ID allocated to the device. This was part of the code I back-ported and submitted a year ago last June.
