    Hi,

    Two days ago, I upgraded the s390x ci.debian.net host from bookworm to trixie. The system was already running the kernel from backports, so
    the upgrade was mostly of the userland. That upgrade hasn't been a
    nice experience, because the system failed to boot afterwards. I was
    able to boot the previous kernel eventually, but while trying to
    figure out if the initramfs was somehow missing pieces I tried to run lsinitramfs on both the old (current) and new (failing) initramfs, but
    that failed on the old one:
    $ lsinitramfs /boot/initrd.img.old
    cpio: premature end of archive
    [...]

    Are you quite sure this is actually the old, working, initramfs? (What
    is that a xymlink to?)

    The current version of initramfs-tools (0.148.1) has a rewritten
    unmkinitramfs and an autopkgtest script for it. But the implementation
    in 0.147 also passes all test cases except those where all component
    archives are uncompressed, which is not something initramfs-tools ever generated.

    Does the new implementation of unmkinitramfs work any better on the
    working initramfs image?

    If not, can you upload the image somewhere for me to inspect?

    Ben.

    I could have sworn that I checked this, but is seems that

    doesn't work on the symlink, but does work on the actual file.
    Interesting for initrd.img (the new one) it doesn't matter if I
    point at
    the symlink or the file.


    Seems like this is a duplicate of bug 1015954, which even has a patch
    and maybe is moot with the new version in stable.

    Right. Thanks for working that out.

    Ben.
