logging output of a cronjob

Dear List,

I have an every-minute cronjob that, once in a while, produces a lot of
output; I'd like to save this output using multilog;

I decided to do like that:

	$ crontab -l | grep xyz
	* * * * * setlock xyz/LOCK xyz/main

	$ cat xyz/main
	#! /bin/sh
	if <CERTAIN-CONDITION>
	then
	  <DO-SOMETHING> | multilog /var/log/xyz
	fi

	$ _

I've never heard of someone using multilog this way;
any pitfalls that I should be aware of?

is there a recommended way to prevent 2+ instances of multilog from
using the same dir?

is there a way to force multilog to wait for /var/log/xyw/lock instead
of exiting with code 111?

someone suggested (many years ago) supervising a script like that...
	#!/bin/sh
	test -p my-pipe || mkfifo my-pipe
	exec cat my-pipe
...and sending to-be-logged-data to my-pipe; seems to me to be a good
idea (although a bit too complex);

any comments?

[]s,
