In a clean chroot, populated with debootstrap for "trixie", run ``` apt install linux-image-amd64 plymouth-theme-mobian ``` Result: ``` [...] Setting up linux-image-6.12.32-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 is what happens here: 1. Another package is installed that calls "update-initramfs -u". This activates the trigger, and we store a timestamp for it. 2. linux-image-6.12.32-amd64 is installed. This calls the initramfs-tools hook which synchronously builds the initramfs. 3. plymouth-theme-mobian is installed. This activates the trigger through a triggers control file. 4. The trigger runs and passes the timestamp from (1) through to update-initramfs. update-initramfs sees the current image is newer than that, and skips the update. We correctly handle the case where the trigger is only activated through `update-initramfs -u`, or only through a triggers control file or direct invocation of dpkg-trigger. But when both methods are used, this bug is possible because a timestmap file is present and it is wrong. So revert the optimised trigger handling until dpkg itself records timestamps for trigger activation (see https://bugs.debian.org/1099136).
