[Bug 1462788] Re: Initrd is not gzip archive

[Andy Whitcroft]

This is a correctly formed initramfs.  An innitramfs is not simply a
compressed cpio archive, it is a set of cpio segments which may
optionally be compressed.  lsinitramfs should correctly show the
combined form.

Title:
  Initrd is not gzip archive

Status in initramfs-tools package in Ubuntu:
  Invalid

Bug description:
  The seems to be an error in the intel_microcode hook for initramfs update.
  This breaks the initrd:

  # file /boot/initrd.img-3.19.0-18-generic 
  /boot/initrd.img-3.19.0-18-generic: ASCII cpio archive (SVR4 with no CRC)

  This is not the expected gzip file. I am not sure now, whether my
  system is bootable.

  Edit /usr/share/initramfs-tools/hooks/intel_microcode. Put an "exit" right after the comment header.
  This will disable the hook and generate a gzipped cpio archive.

  Xubuntu 15.04
  initramfs-tools  0.103ubuntu15

  I also checked an AMD-maschine. No Problems with the initrd.
