yann@1: Backport a bugfix from glibc-2.2.5 to glibc-2.2.2 for the following problem:
yann@1:   When syslog-ng is restarted (or HUPed), vixie-cron (and probably other
yann@1:   programs) stop logging to syslog.

yann@1: 2001-08-27 Ulrich Drepper <Drepper@redhat.com> * misc/syslog.c (vsyslog):
yann@1:   Try a bit harder to use syslogd.  If the connection went down after we
yann@1:   first used it try to connect again and resend the message before printing
yann@1:   to the console.
