make-autoinst-initrd - create initial ramdisk for system autoinstaller
make-autoinst-initrd [--arch ''arch''? kernel_package
make-autoinst-initrd creates an initalization ramdisk for use by the operating system autoinstaller. It takes a single, mandatory argument: the Kernel package containing the kernel to be used for the initrd and floppy boot environment. If an autoinstall disk for another architecture is needed, then the --arch argument can be given to specify the architecture.
The initialization ramdisk consists of a compressed ext2 filesystem, and is left in the current directory as initrd.gz . This file is typically placed (by make-autoinst-disk(1)) on a floppy disk or other medium accessible by the bootloader used by the autoinstaller.
