Subject: Make sure /proc/$$/fd exists.
X-Git-Tag: 4.6.0~212
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4a4cf41b9a51a04886d555aff46a608fef1fe0a3;p=thirdparty%2Fstrongswan.git

Make sure /proc/$$/fd exists.

This avoids the error message generated by enumerator_create_directory().
