Hi,
These patchs allows the user create the following directdisk-multi-rootfs.wks
file:
part /boot --source bootimg-pcbios --ondisk sda --fstype=msdos \
--label boot --active --align 1024
part / --source rootfs --ondisk sda --fstype=ext3 --label primary --align 1024
part /standby --source rootfs --rootfs=<special rootfs directory> \
--ondisk sda --fstype=ext3 --label secondary --align 1024
bootloader --timeout=0 --append="rootwait rootfstype=ext3 video=vesafb
vga=0x318 console=tty0"
The special thing is the /standby partition. Which using rootfs with
a extra '--rootfs' argument instruct the RootfsPlugin what should be
the rootfs directory to be used to create the partition.
It is a very simple features that let users to customize your partition
setup. I thought in the case where we have two rootfs (like active and
standby, e.g used to software update). Or the odd cases when a special
partition need to be create to hold whatever files.
The workflow of wic use remains the same. All the config needs to be done
in .wks file.
To test I used <special rootfs directory> as a rootfs created by 'bitbkae
core-image-minimal-dev'
(e.g:
/srv/build/yocto/master/tmp/work/genericx86-poky-linux/core-image-minimal-dev/1.0-r0/rootfs).
Thanks.
