[opensuse-kernel] Disk space requirement of KOTD build from source
Today I run out if diskpscae when building a KOTD with "default" configuration from sources. I found that the build now nees 3.5G disk space. the same build of 2.6.27.7-9 only needs 888M. The installation also need much more spae than before : rw-r--r-- 1 root root 2511648 29. Jan 04:35 vmlinuz-2.6.27.13- HEAD_20090128193548_5c4d0ded-default -rw-r--r-- 1 root root 2576096 5.

Very likely you build with CONFIG_DEBUG_INFO and didn't stripped the .debuginfo sections from all the kernel modules. In the buildservice and in the shipped product we strip this debuginfo into "debug"-subpackages (debuginfo, debugsource). On doubt just run: # objdump -h /lib/modules/2.6.*/kernel/sound/soundcore.ko | grep debug_info If you don't plan to use kdb, crash, lcrash, systemtap, gdb, ... or so then you might want to build with CONFIG_DEBUG_INFO=n Or you can look into "objcopy" how to strip manually the debuginfo sections. best regards, Daniel -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

Yeah, it's likely the modules aren't having their debug_info sections removed during installation. CONFIG_DEBUG_INFO=y is part of the spec file and has been for years, so the issue isn't just that it's enabled. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAkmB8mYACgkQLPWxlyuTD7LFtACgngJhFJCZmbD50nGOI2ZA+3/p QjQAn0kiOQjGdQyIwlASeEBllNiLMyNE =FhHX -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org

That was to fix a discrepancy between the shipped .config and the one actually used for compilation.

Ah ok, yeah. That's what's changed. The config files in kernel-source now reflect that. The stripping of the debug_info sections is something that happens automatically as part of the rpm build process though. I'm not actually sure how to do it manually. You're probably better off just disabling it in .config. - -Jeff - -- Jeff Mahoney SUSE Labs -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.9 (GNU/Linux) Comment: Using GnuPG with SUSE - http://enigmail.mozdev.org iEYEARECAAYFAkmCF2EACgkQLPWxlyuTD7IEwgCfao0UJ1DaCuCkjTYHQcJ76nnC 59wAnjtulva+tkjkWQIVveF7xLOTS1gU =qYuH -----END PGP SIGNATURE----- -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-kernel+help@opensuse.org
