In fact it happens with sid, with ppc64 too, but not with m68k and sh4. And only with "unshare --pid --fork". Without "unshare", the result is: Unsupported ioctl: cmd=0x80047476 bash: cannot set terminal process group (11507): Function not implemented bash: no job control in this shell Unsupported ioctl: cmd=0x80087467 Unsupported ioctl: cmd=0x80087467 Unsupported ioctl: cmd=0x802c7415 Thanks, Laurent
