Public bug reported: I am running Ubuntu 18.04.4
I am looking at the initrd found in the desktop live cd (<cd loop mount>/casper/initrd). If you execute `binwalk initrd`, binwalk informs that the initrd file contains 2 cpio archives and a lzma archive The first cpio archive is supposed to contain kernel/x86/microcode/AuthenticAMD.bin The second cpio archive is supposed to contain kernel/x86/microcode/GenuineIntel.bin The third file is a LZMA compressed data Now, if you execute `unmkinitramfs <cd loop mount>/casper/initrd new- directory` , you will see 2 directories, "early" and "main". "early" has the AuthenticAMD.bin, which means it corresponds to the first cpio. "main" is the actual initial ram disk file system, which comes from the LZMA compressed data. What I expect to see is also the GenuineIntel.bin firmware. `binwalk` says it's there, but `unmkinitramfs` is not able to extract it out. Why? I see binwalk is at version 2.1.1-16, while initramfs-tools-core (which provides unmkinitramfs) is at version 0.130ubuntu3.9. How do I extract the ubuntu 18 initramfs and get all the contents that binwalk is able to see? ** Affects: initramfs-tools (Ubuntu) Importance: Undecided Status: New ** Tags: initrd ** Summary changed: - unmkinitramfs in initramfs-tools-core doesn't fully extract an initrd + unmkinitramfs in initramfs-tools-core doesn't fully extract an initrd in bionic -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1884079 Title: unmkinitramfs in initramfs-tools-core doesn't fully extract an initrd in bionic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/1884079/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
