[WIC] Update disk layout with etc,var,home as exteral folder

In this layout, the rootfs partition doesn't have the follow folders:

EXTERNAL_ROOTFS_FOLDERS = "
var/
etc/
home/
"

With the follow partitions:

  • datafs -> contains etc/ and var/ folder
  • varfs -> contains var/ fodler

part / --source edgehog-system-partition --ondisk mmcblk --fstype=ext4 --label datafs --size 128M --align 4 part / --source rootfs --rootfs-dir=${IMAGE_ROOTFS}/var --ondisk mmcblk --fstype=ext4 --label varfs --size 128M --align 4 part / --ondisk mmcblk --fstype=ext4 --label appfs --size 32M --align 4

Note: var/ is not used like the other because it doesn't work that way. From empirical evidence, we have a working rootfs if the content of the var folder is placed directly into the root folder of an external partition.

This partition was mounted into /etc/edgehog/folder. Now etc is a folder external to the rootfs partition and is mounted by the init into ramfs image.

[WIC][CLASS] Add EgehogSystemPartitionPlugin class

Add a new WIC's class used as plugin. This class allows to export one or a set of folders from the rootfs and place them into an external partition that inherits that class.

To specify the folders to export this variable have to be populated:

EXTERNAL_ROOTFS_FOLDERS

An example of export of folders /etc, /home and /var:

EXTERNAL_ROOTFS_FOLDERS = "
var/
etc/
home/
"

The partition is setting is:

part / --source edgehog-system-partition --ondisk mmcblk --fstype=ext4 --label datafs --size 128M --align 4

Automatically, this partition will include the folders etc,var and home in its root folder.
