Hi,
A customer has seen a "Can't assign requested address" error from
syslogd(8) at boot time and then sending messages per UDP did not
work. It is a carp(4) setup.
So I would suggest to add EADDRNOTAVAIL to the error numbers that
are ignored when doing UDP sendto(2). Otherwise syslogd would no
longer send to this destination after the error occured once.
ok?
