I assume you're talking about those hook scripts being run while the packages they belong to are only unpacked? I hadn't thought about this issue, but it seems to me that those hook scripts generally ought to be fixed to handle this case properly. Most of the packages installing hook scripts for kernel packages are not going to be dependencies of linux-image packages, so it will never be safe for them to assume their package has been fully installed. > Different debian-based distros use different values for the missing > fields.

This customisation mechanism seems too powerful to be maintainable. There is a high risk that it would conflict with later improvements to builddeb, either resulting in regressions or blocking those improvements from being made. > for example: > make \ > KDEB_OPTS_IMAGE=\ > "-DDepends='initramfs-tools | linux-initramfs-tool, kmod, linux-base'" \ [...] The maintainer scripts generated by builddeb currently don't run depmod or any of the script in linux-base. So this seems like a bad example. However, the dependency on initramfs-tools is an important one that can't simply be inferred from the kernel configuration. So I would support adding a means to append to the Depends field specifically. Appending to the Breaks field may also be useful, as new kernel versions may break specific utilities or user-space drivers. Ben. -- Ben Hutchings When in doubt, use brute force. - Ken Thompson
