Bug#664171: initramfs-tools: initrd cannot be easily disabled when not using kernel-package

[Petr Baudis <pasky@ucw.cz>]

Package: initramfs-tools
Version: 0.100
Severity: normal
Tags: patch

Dear Maintainer,

when creating kernel package by other means than make-kpkg
(e.g. using the kernel's make deb-pkg target), initrd creation
cannot be disabled easily, since the appropriate script checks
whether $KERNEL_PACKAGE_VERSION is set, for a reason that seems
entirely unclear to me. The patch below removes the superfluous
check:


diff --git a/kernel/postinst.d/initramfs-tools b/kernel/postinst.d/initramfs-tools
index 76bb7ee..42474c7 100755
--- a/kernel/postinst.d/initramfs-tools
+++ b/kernel/postinst.d/initramfs-tools
@@ -9,8 +9,8 @@ if [ -z "${version}" ]; then
 	exit 2
 fi
 
-# exit if custom kernel does not need an initramfs
-if [ -n "${KERNEL_PACKAGE_VERSION}" ] && [ "$INITRD" = 'No' ]; then
+# exit if kernel does not need an initramfs
+if [ "$INITRD" = 'No' ]; then
 	exit 0
 fi
 


(As a followup, I have a straightforward patch for the kernel ready
that allows easily disabling initrd when invoking make deb-kpkg;
but the patch cannot work as-is before this change without also
setting fake KERNEL_PACKAGE_VERSION, which might confuse some other
script.)
