Just a stab in the dark, but: The changelog history for linux-image-5.18.0-4-amd64, on my system, gives the change from 5.17 to 5.18 as having happened in May of 2022. The changelog for initramfs-tools, on my system, shows exactly one version newer than May of 2022, released in July of 2022. The changelog for that version of initramfs-tools (0.142) includes the entry: [ Dimitri John Ledkov ] * [d8c5864] mkinitramfs: decompress compressed kernel modules with no reason or other information given. (There are a few other changes listed, which could also be relevant, but seem less obviously so from the brief descriptions - although it is of course hard to judge.) Just at first blush, it looks like something like that could produce an increase in size, potentially a notable one. (The previous version's changelog entry also switches compression to zstd, but that version came out in April, so it's unlikely to be the culprit.) -- The Wanderer The reasonable man adapts himself to the world; the unreasonable one persists in trying to adapt the world to himself.
