[Bug 1300026] [NEW] Enlistment/commissioning boot no longer works

[Jeroen T. Vermeulen]

Public bug reported:

In my MAAS test setup, nodes now fail to enlist or commission.  They
used to work, I think before we changed to the new import script.

Both for enlistment and commissioning the nodes netboot properly, as far
as I can see, but they fail to do what they booted for.  They never
contact the region controller API, and don't rsyslog.

Here's what I see on the console:

Eventually it drops me into a busybox-style shell.  There's some lspci-
style output, followed by:

«
Gave up waiting for root device.  Common problems:
 - Boot args (cat /proc/cmdline)
   - Check rootdelay= (did the system wait long enough?)
   - Check root= (did the system wait for the right device?)
 - Missing modules (cat /proc/modules; ls /dev)

Here's what I get from /proc/cmdline:
