diskimage-builder/elements/ironic-agent/cleanup.d/99-ramdisk-create
Lucas Alvares Gomes ba808fa6ec ironic-agent element to output a .kernel file
The ironic-agent element is created using the disk-image-create utility
(even being a ramdisk) and outputs a .vmlinuz file for the kernel
(different than the ramdisk-image-create which outputs a .kernel file
for the kernel). This is inconsistent and make scripting against the
diskimage-builder more complicated if one wants to support different
types of ramdisk.

This patch creates a hard link for the .vmlinuz file to a .kernel file
at the end of the process (to keep backward compatibility) and print a
deprecation message.
