Tracing through init transitions

["Alan D. Brunelle" <alan dot brunelle at hp dot com>]

I'm trying to trace the opening of files under /proc & /sys during the 
transition from single-user to run level 3, but either the tracing 
doesn't start or gets killed. I've tried various means of trying to 
daemonize the systemtap run (including starting this via an rc script 
utilizing the "daemon" function, and trying the -F option), but nothing 
I've tried seems to work.

Any suggestions?

Thanks (please CC me as I'm no longer on the systemtap mailing list),
Alan
PS. I've attached the script, although I doubt there's anything 
particular in there that would make a difference...
#! /usr/bin env stap

global opens[4000]

function print_opens() {
	foreach ([exe, fn, wr] in opens-) {
		if (wr) str = "WR"
		else	str = "RD"

		printf("%4d %-20s: %s %s\n", opens[exe, fn, wr], exe, str, fn)
	}
}

probe kernel.function("sys_open") {
	fn = user_string($filename)
	if (substr(fn, 0, 6) == "/proc/" || substr(fn, 0, 5) == "/sys/")
		opens[execname(), fn, $flags & 1] ++
}

probe end {
	print_opens()
	exit()
}
