Julia Kreger 7bf70725a6 Create random character devices so systemd does not crash 
Systemd, depending on the version and the configuration,
can attempt to open urandom when a ramdisk boots, before
the udevd is launched to handle the devices. In particular
in FIPS mode, this can result in the ramdisk crashing.

In order to handle this, we pre-create the chracter device
files which can be statically used in the early start sequence
to allow the agent to boot and deploy.

ironic-ramdisk-base

This is a base element for ironic ramdisks. It does not install anything, just takes the prepared images and extract kernel/ramdisk from it.

Configurable Environment Variables

  • DIB_IPA_COMPRESS_COMMAND defaults to gzip, may be set to any valid compression program usable for an initramfs
  • DIB_IPA_MINIMAL_PRUNE defaults to 0 (false). If set to 1, will skip most ramdisk size optimizations. This may be helpful for use of packages with IPA that require otherwise-pruned directories or files.
