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.
