Update pungi-make-ostree to supourt sub-command 'tree', which is just
as the original feature of pungi-make-ostree to compose OSTree tree.
With the change we can add other sub commands later to build other
OSTree artifacts, like the installer image.
Inaddtional to the change, now the the 'tree' command can accept an
optional '--extra-config' parameter to update the original tree
configuration with extra configurations specified in a json file
before composing the OSTree tree.
Example:
pungi-make-ostree tree --repo=/ostree --treefile=/path/to/treefile \
--log-dir=/path/to/log --extra-config=/path/to/extra-config.json
The extra-config file can contains the same configuration as OSTree
phase, the difference is it doesn't understand variant UID as source
repo since it's not ran in the chain of phases. A valid configuration
can be like:
{
"source_repo_from": "http://example.com/repo/x86_64/Server",
"extra_source_repos": [
{
"name": "optional",
"baseurl": "http://example.com/repo/x86_64/optional",
"exclude": "systemd-container",
"gpgcheck": False
},
{
"name": "extra",
"baseurl": "http://example.com/repo/x86_64/extra",
}
],
"keep_original_sources": True
}
The OSTree phase is updated to move out the task of updating treefile,
instead of that, it writes the extra configurations to a json file,
then 'pungi-make-ostree tree' will take it by option '--extra-config'.
