[Libguestfs] guestfs_mount_local api test: have to 'mount' before calling it?

[Richard W.M. Jones]

See the example program here:

https://github.com/libguestfs/libguestfs/blob/master/examples/mount_local.c

----------------------------------------------------------------------
$ ./run ./examples/mount_local /tmp/test.img

This is the 'mount-local' demonstration program.  Follow the
instructions on screen.

Creating and formatting the disk image, please wait a moment ...

The _current directory_ is a FUSE filesystem backed by the disk
image which is managed by libguestfs.  Any files or directories
you copy into here (up to 512 MB) will be saved into the disk
image.  You can also delete files, create certain special files
and so on.

When you have finished adding files, hit ^D or exit to exit the
shell and return to the mount-local program.

sh-4.2$ ls
lost+found
sh-4.2$ ls -l
total 12
drwx------. 2 root root 12288 May 13 22:49 lost+found
sh-4.2$ cp -r /usr/share/doc/libguestfs-devel-1.17.36 .
sh-4.2$ exit

Any files or directories that you copied in have been saved into
the disk image called '/tmp/test.img'.

Try opening the disk image with guestfish to see those files:

  guestfish -a /tmp/test.img -m /dev/sda1

$   guestfish -a /tmp/test.img -m /dev/sda1

Welcome to guestfish, the libguestfs filesystem interactive shell for
editing virtual machine filesystems.

Type: 'help' for help on commands
      'man' to read the manual
      'quit' to quit the shell
