That's a difference between Fedora's initrd and Debian/Ubuntu's 
initramfs-tools then. We do respect the mount options in fstab for the 
root partition when root is mounted from the initrd:

$ cat /etc/fstab | grep " / "
/dev/mapper/main-root /      ext3    relatime,errors=remount-ro 0       1

$ mount | grep " / "
/dev/mapper/main-root on / type ext3 (rw,relatime,errors=remount-ro)

$ cat /proc/cmdline
root=/dev/mapper/main-root ro vga=791 quiet

Cheers,
FJP
