Bug#747893: Please standardize the shared memory directory

[Laurent Bigonville <bigon@debian.org>]

Package: libxshmfence
Version: 1.1-2
Severity: important

Hi,

The libxshmfence package is explicitly setting the shared memory
directory to /tmp (with-shared-memory-dir) while the xorg-server lets
the configure script autodetect it (and then ends up using /run/shm).

These two package should probably use the same directory.

I would propose to use /dev/shm as it is the defacto-standard (eglibc
is using this), standard with the FHS and mounted by all the initsystem
(either directly or with a symlink).

Cheers,

Laurent Bigonville
