Package: initramfs-tools Version: 0.148.2 Severity: normal Dear Maintainer,
When installing a kernel package and a package with a trigger for update-initramfs in one go, the update of the initramfs is skipped in some cases. In a clean chroot, populated with debootstrap for "trixie", I ran apt install linux-image-amd64 plymouth-theme-mobian Result: [...] Setting up linux-image-6.12.32-amd64 (6.12.32-1) ... I: /vmlinuz.old is now a symlink to boot/vmlinuz-6.12.32-amd64 I: /initrd.img.old is now a symlink to boot/initrd.img-6.12.32-amd64 I: /vmlinuz is now a symlink to boot/vmlinuz-6.12.32-amd64 I: /initrd.img is now a symlink to boot/initrd.img-6.12.32-amd64 /etc/kernel/postinst.d/initramfs-tools: update-initramfs: Generating /boot/initrd.img-6.12.32-amd64 Setting up linux-image-amd64 (6.12.32-1) ...

Processing triggers for initramfs-tools (0.148.2) ... update-initramfs: /boot/initrd.img-6.12.32-amd64 has already been updated since Mon Jun 23 06:07:09 2025. # The initramfs is updated after setup of the kernel package. It is NOT updated again after setup of package plymouth-theme-mobian, which is wrong. The files that are installed by package plymouth-theme-mobian are missing in the initramfs (and the plymouth splash screen will not work). This behaviour was introduced in version 0.147 by: [7f2ed35] Avoid updating the initramfs twice for some cases (LP: #1466965) My use-case is that I install the kernel package and plymouth-theme-mobian during an image build that runs in a debootstrap chroot. I could work around the issue by manually calling "update-initramfs -u" at the end of the image build, or by calling update-initramfs in the postinst script of plymouth-theme-mobian (instead of defining a dpkg trigger). I consider both ways as workarounds and the new behaviour of update-initrafms as a bug. Note that I'm not a Mobian developer nor do I use that package. I have a custom package that defines a trigger in the same way as plymouth-theme-mobian where I observe the issue. Tobias
