[OE-core] [PATCH 0/5] wic: Add --rootfs option to --source param

[João Henrique Ferreira de Freitas]

Hi Tom,

Let's back in this context. This is really important and I was waiting 
to complete the previous stage.

I have been working on it since Otavio's concerns about 'contents which 
are not tracked'.

So extending my previous patches (80% done) to handle this situation is 
quite easy. Like this:

bitbake directdisk-multi-image-e img1=core-image-minimal -e 
img2=core-image-minimal -e img3=core-image-minimal

directdisk-multi-image.wks:

part /boot --source bootimg-pcbios --ondisk sda --fstype=msdos --label 
boot --active --align 1024

part / --source rootfs --image-name=img1 --ondisk sda --fstype=ext3 
--label primary --align 1024

part /standby --source rootfs --image-name=img2 --ondisk sda 
--fstype=ext3 --label secondary --align 1024

part /root --source rootfs --image-name=img3 --ondisk sda --fstype=ext3 
--label root_sec --align 1024


If the user put '--image-name' and '--rootfs-dir' the '--image-name' 
takes precedence.

As wic is a generic tool, the user could prefer to use images from OE or 
any other rootfs-dir.

Tom, what do you think? Could I go ahead?

Thanks
