Package: dkms
Version: 3.2.2-1
dkms ships a /etc/kernel/header_postinst.d/dkms file, which I suppose is
expected to run when the linux-headers postinst scripts call:
linux-run-hooks headers postinst $version -- "$@"
However, linux-run-hooks doesn't use /etc/kernel/header_postinst.d, only
/etc/kernel/headers_postinst.d, so the shipped
/etc/kernel/header_postinst.d/dkms is never run.
(I verified this by adding --verbose --debug to the run-parts invocation in
linux-run-hooks.)
This is an uncommunicated (maybe even unintended) path change on the
src:linux side. Older kernels had this in linux-headers-*.postinst:
system ("run-parts --report --exit-on-error --arg=$version " .
"/etc/kernel/header_postinst.d") &&
die "Failed to process /etc/kernel/header_postinst.d";
This change went unnoticed so long since nowadays linux-headers-*
depends on linux-image-* which already triggers dkms via
/etc/kernel/postinst.d/dkms (making
/etc/kernel/header{,s}_postinst.d/dkms more or less a no-op).
