features:
- By default, the ironic-conductor service caches the node's deploy
ramdisk and kernel images locally and serves them via a separate
HTTP server. A new ``[pxe]/ipxe_use_swift`` configuration option
(disabled by default) allows images to be accessed directly
from object store via Swift temporary URLs.
This is only applicable if iPXE is enabled (via ``[pxe]/ipxe_enabled``
configuration option) and image store is in Glance/Swift.
For user images that are partition images requiring non-local boot,
the default behavior with local caching and an HTTP server
will still apply for user image kernel and ramdisk.
