Test Case

* Steps
1) preparation
...
one target: atom-pc
two usb sticks: one for boot and install, another for plug test, they are both vfat filesystem.
...

2) config 
conf/local.conf:
...
MACHINE ?= "atom-pc"
...

3) build image
bitbake core-image-sato

4) load image to atom-pc
Test Case TC-2927: boot and install from usb 

5) open a terminal/ssh of atom-pc
Test Case TC-2955: remote access by ssh 

6) hotplug test: usb stick with vfat filesystem is accessible
Test Case TC-2947: usb mount
Test Case TC-2950: usb write files
Test Case TC-2948: usb read files
Test Case TC-2949: usb umount

7) coldplug test: usb stick with vfat filesystem is accessible
plug usb stick
boot system
create files in usb
view files in usb by file browser

8) use systemd for the main image and use sysvinit for the rescue image
Modify conf/local.conf, and repeat step 3 to 7;
...
DISTRO_FEATURES_append = " systemd"
VIRTUAL-RUNTIME_init_manager = "systemd"
...

9) use systemd exclusively
Modify conf/local.conf, and repeat step 3 to 7;
...
DISTRO_FEATURES_append = " systemd"
VIRTUAL-RUNTIME_init_manager = "systemd"
DISTRO_FEATURES_BACKFILL_CONSIDERED = "sysvinit"
...

* Expected Results:
1) build image success

2) the owner of plugin usb stick is `xuser', it will be automatically
mount/umount, and xuser could read files from usb and write files to it.
