  Testing on s6-linux-init shows that a SIGWINCH is sent to
s6-svscan on kbrequest after s6-linux-init has performed the ioctl.
So, the answer seems to be yes.

  Having device state changes not survive execve() would be a very
unfriendly, un-Unixy design. I don't doubt there are some of those
out there, but apparently this isn't one of them.
