Libguestfs - Mar 2012 - modifying open_guest function (copy_over.c)

It works, but I should delete

if (guestfs_umount_all (destg) == -1)
??? exit (EXIT_FAILURE);

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))

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