Re: Query on s6-log and s6-supervise

Apologies, I'd implied that we have multiple s6-supervise processes
running and their children pipe to one file which is read by one s6-log

You can achieve this outcome by using s6-rc's, where one consumer can
receive multiple inputs from producers.

There is a special (but not unique) case where a program, such as apache
which will have explicit log files (defined in apache's config file) to
record web-page accesses and error logs, on a per server basis. Because
all the supervised apache instances can write to one error logfile, I
instructed apache to write to a pipe. Multiple supervised apache
instances using the one pipe (aka funnel), which was read by one s6-log.
 This way reducing the number of (s6-log) processes. I could do the
same with the access logs and use the regex function of s6-log, but I
tend to simplicity.
