I understand the constraints of the various platforms, and imagine quite well some things are much important. But I thought it won't be difficult to "make a tweak" whether using a syslogd package or adding a line anywhere in a config file to redirect those lines… i don't know! I just thought someone already had the problem to raise!
I mean, my firewall is to be fanless soon, and if I can keep the room clean of any noise, leaving vpn access and logging facilities (which need another fanless computer then...), it would be great!
Considering kiwi, it's great, but windows stations are always to be rebooted one day or another because it acts slowly or whatever reason, so I will lose that period of logs... Besides, two computers crashes more often than one (especially if one is windows)! With this ability to keep logs, in my mind (which I admit not to be always clear!!), the firewall is independent and makes his (very good) work alone.
Let me add, I'm probably not able to write any patch, especially for all platforms ;-) I respect your work and don't want to change the way you do or think. It's already very kind of yourself to take time to answer and I do thank you :-)
