Looks like a big push for this was for embedded devices, android, etc. Since I read that it may give a boot time speed up, I was slightly intrigued. http://lkml.org/lkml/2009/4/30/182, yes…it is an old topic but it finally was released in stable .32 kernel.

So, bootcharts:
bootchart-2.6.31.6.png 39 seconds
bootchart-2.6.32-no-devtmpfs.png 37 seconds
bootchart-2.6.32-devtmpfs.png 37 seconds
bootchart-2.6.32-openrc.png 26 seconds (devtmpfs)

So, where is the real win here? Well, as I wrote before, use openrc.

Especially if you enable rc_parallel="YES" in /etc/rc.conf. Anyway, others have wrote about it already, including a bootchartd of before and after here.

Anyway, this should be hitting stable soonish and when it does be sure to read the migration guide because some things have indeed changed.

For me, I count to 10 slowly and my laptop is at the xdm prompt…very cool and good job Roy!
