Hmm, both should be sufficient, however initrd seems to be not loaded. What does
your grub config says and could you zcat [initrd] | cpio -t (or whatever it is
packed by)?

If you have your /etc/mtab file on ro mounted partition while in recovery mode,
it's not being updated by mount...

Is the real reason EBUSY (as it should be) -- could you strace your mount command?
