Bug#702625: linux-source-3.2: Custom kernel built from Debian source gives a package with huge size

[Frédéric Boiteux <fboiteux@free.fr>]

Package: linux-source-3.2
Version: 3.2.35-2
Severity: normal

Dear Maintainer,

  Upgrading from Squeeze to Wheezy and using TuxOnIce hibernation system,
I installed the Wheezy's linux-source-3.2 package, and build a cusom kernel
following recommendations as in :
http://kernel-handbook.alioth.debian.org/ch-common-tasks.html#s-common-building
(I used to do this also on my Squeeze system).

I applied the TuxOnIce and RT patches, copy the config of the Debian package linux-image-3.2.0-rt-amd64, done a 'make oldconfig' to answer new config about TOI,
and run the compilation with :

time ionice -c 3 nice env KBUILD_PKG_ROOTCMD="fakeroot -u" make -j 3 KDEB_PKGVERSION=3.2-3.2.35-2 KERNELRELEASE=3.2-rt-toi deb-pkg

After a while, I get a debian package, but with a huge size, about 500 MB,
whereas official Debian is about 20 MB !
It seems the modules are built with symbols. Looking around on the web,
I saw people telling to look at CONFIG_DEBUG_INFO config parameter, and
it's actually set :

$ grep CONFIG_DEBUG_INFO .config
CONFIG_DEBUG_INFO=y
# CONFIG_DEBUG_INFO_REDUCED is not set

But it's also set in the official Debian configs :

$ grep CONFIG_DEBUG_INFO /boot/config-3.2.0-4-*
/boot/config-3.2.0-4-amd64:CONFIG_DEBUG_INFO=y
/boot/config-3.2.0-4-amd64:# CONFIG_DEBUG_INFO_REDUCED is not set
/boot/config-3.2.0-4-rt-amd64:CONFIG_DEBUG_INFO=y
/boot/config-3.2.0-4-rt-amd64:# CONFIG_DEBUG_INFO_REDUCED is not set

What should I do to get a 'standard size' Debian package ?
Disable this parameter in the kernel config ? Or doing an action / setup
I forgot ?

  Thanks for your support,
	Fred.
