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. --- init/init.c | 4 ---- 1 file changed, 4 deletions(-) diff --git a/init/init.c b/init/init.c index e6fd0e6..aa6c25f 100644 --- a/init/init.c +++ b/init/init.c @@ -240,10 +240,6 @@ main () /* Make current process the controlling process of the tty. */ setsid (); -#ifdef TIOCSCTTY - if (ioctl (0, TIOCSCTTY, 1) == -1) - perror ("ioctl: TIOCSCTTY"); -#endif if (!quiet) fprintf (stderr, "supermin: creating /dev/root as block special %d:%d\n", -- 2.12.0
