  • LFS - About initial ramdisks

    From Alan Ianson@1:153/757 to Andrew Alt on Fri Feb 24 14:44:22 2023
    Anyone else have a problem with the LFS section on creating an initrd? Me
    and a friend tried the mkinitramfs from https://www.linuxfromscratch.org/blfs/view/svn/postlfs/initramfs.html

    When we ran it, we wound up with a 770Mb file. When we extracted it with cpio, it only extracted about 64K bytes. We tried a few times and the
    results were consistent.

    It only contained a few files, related to microcode (I don't have access to his computer right now so I can't be more specific).

    That sounds like the microcode bits were prepended to the initrd file.

    If that is the case then it's hard to inspect the rest of the contents of that file, at least in the usual way.

    I don't normally use an initramfs but I had one with a gentoo install and I found the same thing. Gentoo's initramfs tool (i forget what it called now) created a huge initramfs but I was only able to see the intel-ucode bits of it when I tried to look inside of it.

    It must have contained a lot of modules but it did boot up just fine.

    It's kind of comforting to know it happened to someone else. :)
