Part of the solution is to create more of them in hurd-boot.scm.
But there=E2=80=99s a second problem: we need to build glibc=E2=80=99s =E2=
=80=98pt_chown=E2=80=99 setuid
program (with =E2=80=98--enable-pt_chown=E2=80=99) so that =E2=80=98grantpt=
=E2=80=99 can change the
owner of /dev/ttyp*.
At least that=E2=80=99s how it=E2=80=99s done on Debian GNU/Hurd, but I=E2=
=80=99m surprised
/hurd/term (for pty-slave) doesn=E2=80=99t just return the right UID on
=E2=80=98io_stat=E2=80=99.
Ludo=E2=80=99.

The =E2=80=98t/malformed-split.sh=E2=80=99 test of Texinfo 6.7 hangs on GNU=
/Hurd (in a
childhurd) as of commit 78f03567f44f704dfbc03cb64368aa42a01e78ad.
The test invokes its =E2=80=98pseudotty=E2=80=99 program, which creates a
pseudo-terminal using =E2=80=98posix=C2=A0openpt=E2=80=99. That call fails=
when not running
as root in a childhurd:
