Automatic merge from submit-queue examples/guestbook/php-redis: don't reopen stdio fds /etc/apache2/apache2.conf was configured to log in this way: > ErrorLog /proc/self/fd/2 > CustomLog /proc/self/fd/1 combined This causes apache to reopen the already-opened fds. It works fine when the file descriptors are pipes or ttys but it fails when they are Unix sockets because sockets cannot be opened with the open() syscall. The issue happens when apache is connected to systemd-journald, like in the rkt container run-time. This patch uses "cat" to directly write to the stdio fds without reopening them. apache2.conf now looks like: > ErrorLog "|$/bin/cat 1>&2" > CustomLog "|/bin/cat" combined It works both with Docker and rkt (tested with and without --interactive). Symptoms: > [ 2673.478868] apache2-foreground[4]: (6)No such device or address: > AH00091: apache2: could not open error log file /proc/self/fd/2.
