Greetings,
I have few apps installed from ports (clamav-milter, spamassassin-milter
and etc)
which should chown/chmod their socket to allow apps running with
different user
to connect to them.
The problem is that I see some race here. On SMP machine very often the app
finish it's execution and next chown/chmod is called, but the socket is
not opened/created at this point.
Which is very annoying because I have to change my rc.d scripts by hand
every time when I update/upgrade.
And sometimes I forget ...
Can you consider the following patch (or if you like something similar)
for inclusion which will then allow
rc.d shell script to call a function to wait for the socket and once
ready to exit and let chown/chmod start.
The function should be called with 2 parameters - socket path and
timeout (and we can manage them from rc.conf)
