In order to prepare shared software packages on the system
controller for subcloud prestaging, the file
"package-checksums" containing a list of packages and
their checksums, must be copied to /usr/local/share/pkg-list
and renamed as packages_list.
The prestaging process needs the package-and-checksum list
for the version of the load on the controller and the version
of the load on the subcloud.
This file needs to be copied over to /var/www/pages/feed/rel-<id>
on the controller so that the subclouds can download it.
This file can be obtained by downloading from the system
controller. If the system is being installed directly from
a boot iso, the appropriate kickstart is called to install
the file from the mounted bootimage.iso.
There are a few cases which determine how to get the file.
Cases:
1. Install load directly from bootimage.iso (both controller and
subcloud) - copy from mounted iso to location. The iso
may be present on a peripheral device like a CD/DVD.
2. Install load over lan - download the file from server and copy
to locations (all controllers)
3. Version upgrade by importing a new load - copy the file
to the appropriate location on the system controller.
The subcloud will download the package_checksums belonging
to the imported load as part of the upgrade process.
Test Plan:
PASS: Verify that the file is copied over to /usr/local/share/
pkg-list and /var/www/feed/rel-<rel-id>/ when installing
System Controller or subcloud from bootimage.iso
PASS: Verify that the file is copied to the locations when
installing controller-1 via pxeboot
PASS: Verify that the file is copied to the locations when upgrading
the System Controller (using load-import)
PASS: Verify that the file is copied when adding a subcloud with
dcmanager subcloud add
