Yup, you don't want that in live code since it'll try to unmount
all your disks (and fail, luckily).

inmain() function and
/* Clean up. */
if (guestfs_umount_all (srcg) == -1) {
pthread_cancel (threaddata->mainthread);
exit (EXIT_FAILURE);
}
in the start_scrthread() function or it will return an error after the program finish:
libguestfs: error: umount_all: umount: /sys/fs/cgroup/systemd: umount:
/sys/fs/cgroup/systemd: device is busy.
(In some cases useful info about processes that use
the device is found by lsof(8) or fuser(1))
