Why not? If the file exists and I start up two syslogd's, there is a race of which one open's the file first. If I start up two syslogd's and the file does not exist and then I touch the file. There will be a race if I ``kill -HUP <pid #1> <pid #2>''. If I take care to HUP only one syslogd, move the file to the side, touch the file again and HUP the second syslogd there is no race. I can similarly take this amount of care with the way I would like syslogd to work such that there is no race. -- -- David ([EMAIL PROTECTED]) To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-hackers" in the body of the message
