Source: linux Version: 5.10.209-2 Severity: wishlist Hi,
is it possible to add support for header_preinst.h hooks (similar to header_postinst.d hooks)? My use case would be dkms. Whenever a linux-headers-$KVERS package gets updated (without changing the package name), we need to rebuild all dkms modules against the new headers. Therefore we need to "invalidate" (e.g. "unbuild" them (in dkms language)) the currently built modules, s.t. dkms will rebuild them. That would better fit to a preinst hook than to a postinst hook. postinst hooks are called from both linux-headers-* and linux-image-* packages, possibly causing two builds (with unbuild inbetween). Also, if postinst hooks failed because a module was not compatible with the updated headers, configuring the header package again after fixing the module package would also rebuild all successfully built modules once again. Therefore I'd prefer to do the invalidation step only once in a header_preinst.d hook. Andreas
