Backport /dev/pts to older branches?

[Aurelien Jarno <aurelien@aurel32.net>]

Dear all,

I would be interested in backporting the following change to Debian
Bullseye package:

commit 27fe5f2e67a0e4cc0526b1b32b55f8e519075edb
Author: Florian Weimer <fweimer@redhat.com>
Date:   Wed Oct 7 14:55:04 2020 +0200

    Linux: Require properly configured /dev/pts for PTYs

    Current systems do not have BSD terminals, so the fallback code in
    posix_openpt/getpt does not do anything.  Also remove the file system
    check for /dev/pts.  Current systems always have a devpts file system
    mounted there if /dev/ptmx exists.

    grantpt is now essentially a no-op.  It only verifies that the
    argument is a ptmx-descriptor.  Therefore, this change indirectly
    addresses bug 24941.

This fixes bz#24941, which seems to affects ansible users. I wonder if I
should backport it in the upstream stable release branch instead. This
is trivial to backport, but on some rare systems, this might require some
changes to get /dev/pts working.

Any thought about that?

Thanks
Aurelien
