The source is FreeBSD 11.0-CURRENT r256450. Unlike previously, now when I boot my BBB it does not probe umass devices until after it goes multiuser. This has created a problem because I am using an external USB hard drive for swap, /usr/src, /usr/obj, and /usr/ports. Because of the new probe order, the devices referenced in /etc/fstab don't exist and the system drops into single-user.

It's supposed to wait for usb enumeration before mounting the root filesystem, unless that tunable is set to 1. -- Ian
