I would definitely have to agree with the desire for being able to HUP for
rotating logs/etc; then again, I don't remember filing an official RFE to
LSoft, probably time to do so.  It would also be an "interesting" change for
them as logging is just performed via a command-line redirection, no logfile handling in the program itself.

It would be pretty trivial to take one of the perl web loggers that accepts
log-data from STDIN and opens a date-based log-file to send it to; but
that, again, would be modifying 'go'.  If I ever get bored I might
implement that, but bored hasn't been in my vocabulary for a while :)

As for implementing home-grown, here's what we've used for, oh, 6+ years.
You just write a wrapper _around_ 'go', and call that in /etc/rc2.d/S*mumble,
and also from cron every night.  It ain't pretty, but it's functional (it
was inherited and worked, so dont ask for reasoning in the PATH, if that
bored thing comes up again, I'll make sure things are sane without ucb [ick]):
