Projects / WrapLinux


WrapLinux is a utility to wrap a Linux kernel, together with a kernel command line and one or more initrd/initramfs files into a single file in ELF or NBI format. This is required by certain boot protocols, such as Etherboot/Netboot, and may otherwise be desired for consistency reasons. It can be considered a replacement for the mknbi and mkelf utilities.

Recent releases

    Release Notes: This release fixes a bug that prevented WrapLinux from being compiled without an executable stack. WrapLinux never needed an executable stack; this was strictly an omission.

      Release Notes: The generation of NBI images with merged segments has been fixed. Merged segments is the norm, so effectively NBI images were broken.

      •  27 May 2008 21:36

        Release Notes: This release adds support for generating Multiboot-compliant ELF files for boot loaders that cannot load ELF files without a Multiboot header. No Multiboot features are actually used, however; it just adds a dummy header.

        •  16 Jan 2008 21:55

          Release Notes: This release maintains the strict limits of initrd subfiles when generating the section headers. It also adds segment coalescing for NBI output, which should prevent errors when generating an NBI with a large number of initrd subfiles.
