Hi,
This may be useful for rc.d people so I've decided to post it here. I
created these graphs with the NetBSD rcorder-visualize script with
some changes to adapt with our needs (e.g. some scripts would provide
multiple services, etc, attached). I think the script is useful for
FreeBSD as well, should we import it?
Generated graph can be found at:
http://people.freebsd.org/~delphij/misc/rcorder-r231173.svg
Or,
https://www.delphij.net/rcorder-r231173.svg
(people.freebsd.org would serve the .svg as a download).
Cheers,
