We also discussed the future +of boot systems, and ways to handle the increasing number of boot +issues introduced by the Linux kernel becoming more and more asynchronous and event base. The Ubuntu approach using udev and upstart might be a good way forward. Time will show.

    On our IRC channel for this effort, #pkg-sysvinit, a new idea was introduced by Raphael Geissert today, one that could affect the startup speed as well. Instead of starting some scripts concurrently @@ -34,10 +44,3 @@ from rcS.d/ and another set of scripts from rc2.d/, it would be possible to run a of them in the same process. A quick way to test this would be to enable insserv and run 'mv /etc/rc2.d/S* /etc/rcS.d/; insserv'. Will need to test if that work. :)
