Yes, you need at least something mounted to / (so /dev/sda1 in your 
example) before calling mount-local. mount-local needs a root filesystem 
mounted and it will always fail without it (in libguestfs 1.26 the error 
message is clear in such cases).

I'm afraid I don't understand what you mean here -- can you please 
provide an actual case of what you want to do?
