Great, I did just that, setup /usr with the installer -- basically stumbled upon a working solution, looks like things would have broken pre-F18...
Nice systemd-analyze results, incredible. What led me to your guide was NetworkManager's wait-online-service, which alone added 30 seconds to boot time! Down to 6 seconds now, and should get under 4 seconds with "sudo dracut -f -H -o plymouth" test that I'll run later today.On Tue, Apr 2, 2013 at 12:34 PM, Harald Hoyer <harald.hoyer@xxxxxxxxx> wrote:

has not enough information or tools or kernel drivers to mount /usr or to
assemble the device it lives on. This case should not be possible, if you set up
/usr with the installer. If you encounter such a problem, then please file a
bug, because dracut (the initramfs framework) should be able to cope with all
supported installation locations.
you are welcome :)

$ systemd-analyze
Startup finished in 6s 730ms 730us (firmware) + 35ms 148us (loader) + 665ms
330us (kernel) + 428ms 948us (initrd) + 1s 598ms 595us (userspace) = 9s 458ms 751us
$ cat /etc/fedora-release
Fedora release 19 (Schrödinger’s Cat).... I need a faster BIOS :)
