wic: Extend --rootfs-dir to connect rootfs-dirs

2014-03-30T09:01:58+00:00

The wic command-line param --rootfs-dir gets generalized to support
multiple directories. Each '--rootfs-dir' could be connected using a
special string, that should be present in .wks. I.e:

wic create ... --rootfs-dir rootfs1=/some/rootfs/dir \
  --rootfs-dir rootfs2=/some/other/rootfs/dir

  part / --source rootfs --rootfs-dir="rootfs1" --ondisk sda --fstype=ext3 \
    --label primary --align 1024

  part /standby --source rootfs --rootfs-dir="rootfs2" \
    --ondisk sda --fstype=ext3 --label secondary --align 1024

The user could use harded-code directory instead of connectors. Like this:

  wic create ... hard-coded-path.wks -r /some/rootfs/dir

  part / --source rootfs --ondisk sda --fstype=ext3 --label primary --align 1024

  part /standby --source rootfs --rootfs-dir=/some/rootfs/dir \
    --ondisk sda --fstype=ext3 --label secondary --align 1024

wic: Report all ROOTFS_DIR artifacts

2014-03-30T09:01:58+00:00

When a .wks has more than one ROOTFS_DIR it's better to report
all ROOTFS_DIR that was used to create the image.

wic: Add SD/MMC-Cards support to '--ondisk' param

2014-03-26T15:06:11+00:00

The special case when wic is set up to use SD/MMC-Cards in place
of sdX disks is not handled properly.

Append 'p' to the rootdev when disk is SD/MMC-Cards fix this situation.

wic: Hook up BootimgEFIPlugin and BootimgPcbiosPlugin plugins

2014-02-04T12:56:55+00:00

Remove all the Wic_PartData and DirectImageCreator code now
implemented by the BootimgEFIPlugin and BootimgPcbiosPlugin plugins,
as well as all the special-cased boot_type code, significantly
cleaning up the code.

Replace the calling code with general-purpose plugin invocations, in
essence calling the appropriate implementations at run-time based on
the --source value in effect.

Change the directdisk.wks and mkefidisk.wks scripts to make use of the
new plugins.

wic: Add wic-specific bootloader subclass

2014-02-04T12:56:55+00:00

Add a new wic-specific bootloader subclass so we can add a --source
param to hang non-partition plugin off of.

By default, the bootloader gets the /boot partition source plugin, but
this can be overridden by the --source bootloader param if needed.

wic: Remove rpmmisc call from livecd

2013-10-23T06:14:00+00:00

We don't currently use LiveCDImageCreator, but it makes calls when
initialized via the plugin interface to rpmmisc module functions,
which we don't want the dependency on.

To make it (and LiveUSBImageCreator) happy, we give it the dummy
"i386" value for now.

wic: Remove rpm and grabber dependencies from BaseImageCreator

2013-10-23T06:14:00+00:00

BaseImageCreator is a base class for DirectImageCreator and others,
and imports rpm and grabber (which imports rpm).

The various plugins e.g. DirectPlugin import the creators and
therefore these dependencies, which manifest at run-time as e.g.:

  Warning: Failed to load plugin imager/direct_plugin: No module named
    rpm

wic: Remove dependency on rpmmisc

2013-10-23T06:14:00+00:00

rpmmisc imports rpm and contains misc rpm utilities related to
packaging and determining arches based on the packaging.  We should
never run across this in the initial version of wic, so remove the
dependency.

wic: Add OpenEmbedded-specific implementation

2013-10-01T21:53:52+00:00

Reuses the mic/livecd infrastructure but heavily subclasses and
modifies it to adapt to the special needs of building images from
existing OpenEmbedded build artifacts.

In addition to the OE-specific mic objects and modifications to the
underlying infrastructure, this adds a mechanism to allow OE kickstart
files to be 'canned' and made available to users via the 'wic list
images' command.

Two initial OE kickstart files have been added as canned .wks files:
directdisk, which implements the same thing as the images created by
directdisk.bbclass, and mkefidisk, which can essentially be used as a
replacement for mkefidisk.sh.  Of course, since creation of these
images are now driven by .wks files rather than being hard-coded into
class files or scripts, they can be easily modified to generate
different variations on those images.  They also don't require root
priveleges, since they don't use mount to create the images.  They
don't however write to media like mkefidisk.sh does, but rather create
images that can be written onto media.

wic: Add mic w/pykickstart

2013-10-01T21:53:38+00:00

This is the starting point for the implemention described in [YOCTO
3847] which came to the conclusion that it would make sense to use
kickstart syntax to implement image creation in OpenEmbedded.  I
subsequently realized that there was an existing tool that already
implemented image creation using kickstart syntax, the Tizen/Meego mic
tool.  As such, it made sense to use that as a starting point - this
commit essentially just copies the relevant Python code from the MIC
tool to the scripts/lib dir, where it can be accessed by the
previously created wic tool.

Most of this will be removed or renamed by later commits, since we're
initially focusing on partitioning only.  Care should be taken so that
we can easily add back any additional functionality should we decide
later to expand the tool, though (we may also want to contribute our
local changes to the mic tool to the Tizen project if it makes sense,
and therefore should avoid gratuitous changes to the original code if
possible).

Added the /mic subdir from Tizen mic repo as a starting point:

 git clone git://review.tizen.org/tools/mic.git

 For reference, the top commit:

 commit 20164175ddc234a17b8a12c33d04b012347b1530
 Author: Gui Chen 
 Date:   Sun Jun 30 22:32:16 2013 -0400

    bump up to 0.19.2

Also added the /plugins subdir, moved to under the /mic subdir (to
match the default plugin_dir location in mic.conf.in, which was
renamed to yocto-image.conf (moved and renamed by later patches) and
put into /scripts.
