[Libguestfs] [PATCH supermin] init: Don't perform ioctl (TIOCSCTTY).
Doing this breaks bash in virt-rescue with the error:
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
Also ^C etc does not work.
Removing this ioctl call fixes this.
I noticed the problem because supermin's init compiled with dietlibc
worked, since the dietlibc header files don't define TIOCSCTTY and
hence the ioctl was not called.
