[Libguestfs] working with mount-local

[Vasiliy Tolstov]

Hi. I'm try to use guestfish inside golang (extract some files from
image and create squashfs from root).
Now i can't understand how can i work with mount-local/mount-local-run.
Where i can specify what partition i'm export to local? Does i need
firstly mount /dev/sda1 to / for example and after that run
mount-local /tmp/xxx ?
Second - i'm work with guestfish via writing to stdin and getting
result from stdout. In case of mount-local-run does i need fully fork
new binary or i can only dup stdin descriptor and work with it?
