Package: schroot
Version: 1.6.10-2
Severity: important

debootstrap recently replaced the /dev/ptmx device node with a symlink
/dev/ptmx -> pts/ptmx[1]. This changed the default permissions from
world-writable (0666) for /dev/ptmx to no-access (0000) in chroots[2].

This causes build failures as, for example, openmpi's mpirun relies on
access to pseudo-terminals.

As chroots used by sbuild/buildd do not need access to the host's
pseudo-terminals, schroot could just mount a private devpts instance
with world-writable ptmx in the chroot: for this replace

  /dev/pts        /dev/pts        none    rw,bind         0       0


  /dev/pts /dev/pts devpts rw,newinstance,ptmxmode=0666 0 0

in the sbuild profile's fstab. To accommodate old chroots that still
have a /dev/ptmx device node, an additional bind mount

  ${chroot}/dev/pts/ptmx   /dev/ptmx   none   rw,bind 0 0

is needed to make sure only the devpts' ptmx device is used. I don't
think this can be done via the profile's fstab, but only via a setup

   [ Simon McVittie ]
   * Instead of creating a /dev/ptmx → pts/ptmx symlink unconditionally,
     try mknod with “c 5 2” parameters first, and fall back to a symlink
     only if it fails. This should help with various tools like pbuilder,
     sbuild, and schroot (Closes: #817236).
   * Add autopkgtest support to test various scenarios.
   [ Cyril Brulebois ]
   * Uniformize COMPONENTS/USE_COMPONENTS handling.
