svn commit: r309625 - head/sbin/rcorder

[Ravi Pokala]

For grins, I ran this on my build server. The resulting graph is... complex. But one thing was immediately clear: neither /etc/rc.d/dhclient and /etc/rc.d/natd depend on anything. That seems wrong: I would expect them to have some sort of dependency on NETWORKING, either BEFORE (since dhclient may be involved in bringing up the network) or REQUIRE (since it doesn’t make sense to run a networking daemon like natd before networking is up).

Or am I missing something?

Thanks,

Ravi (rpokala@)

Log:
  Add rcorder-visualize.sh, which generates graphviz from rc.d scripts
  
  This is imported from NetBSD.  The author--Joerg Sonnenberger--agreed
  to apply a two-clause BSD license, just so the license was clear.
  
  This source tree location matches NetBSD, and is the first place someone
  might look for such a tool.
