Extract a compressed or archive image

  imgextract [--name <name>] [--timeout <timeout>] [--keep] <uri|image>

  imgextract http://192.168.0.1/images/initrd.gz

Extract a single image from an archive image (which may be a compressed single-file archive).

A name for the extracted image can be specified using the --name option. If no name is specified, then a default name will be constructed by stripping any archive suffix (such as .gz for gzip archive images).

A download progress timeout can be specified (in milliseconds) using the --timeout option.

The original archive image will be automatically discarded unless the --keep option is specified.

This command is available only when the build option IMAGE_ARCHIVE_CMD is enabled.

You can use the chain or kernel commands to execute a single-member archive image directly without using the imgextract command. For example, if you have a GZIP-compressed kernel image vmlinuz.gz:

  #!ipxe
  kernel http://192.168.0.1/images/vmlinuz.gz
  initrd http://192.168.0.1/images/initrd.img
  boot
