From afde9a73a0eafb9c52b3d4ce2911692924ea626e Mon Sep 17 00:00:00 2001 From: Eric Wong Date: Thu, 17 Mar 2016 00:27:36 +0000 Subject: doc: reference --keep-file-descriptors for "bundle exec" "bundle exec" alone is not suitable for use with systemd-style socket activation due to Ruby 2.0+ behavior of setting close-on-exec for file descriptors above 2. However, the "--keep-file-descriptors" option was added to bundler 1.4.0 to workaround this Ruby 2.0 change and may be used to prevent Ruby 2.0+ from closing file descriptors on exec.
