Description Stefan Dirsch 2007-08-27 20:10:13 UTC

Due to missing binutils in default patterns, the installation/update of KMPs/kernels no longer work. /usr/lib/module-init-tools/weak-modules used in %post of kernel/KMPs to make sure that kABI compatible kernel modules are symlinked, needs nm of binutils.

Comment 1 Stephan Binner 2007-08-27 20:39:54 UTC

Why do the KMP/kernel packages don't require it if the need it!?

Comment 2 Stefan Dirsch 2007-08-27 21:19:01 UTC

module-init-tools should require binutils. 
/usr/lib/module-init-tools/weak-modules is part of module-init-tools.

Comment 3 Andreas Jaeger 2007-08-28 07:06:13 UTC

Might be related to #304708 (or even duplicate).

Christoph, this means one more package for the media unless binutils is already on  the CDs.

Comment 5 Michal Marek 2007-08-28 08:02:46 UTC

Steffan: thanks for the detailed report. Fixed by adding Requires: binutils.

Comment 6 Stefan Dirsch 2007-08-28 08:03:04 UTC

It's a duplicate. But since Bug #304708 doesn't explain, why this is a problem, I marked Bug #304708 as duplicate of this one.

Comment 7 Michal Marek 2007-08-28 08:04:09 UTC

... and sorry for the double 'f' :)

Comment 10 Stephan Kulow 2007-09-06 12:09:16 UTC

Is there no other way to get the kabi of the .ko then using another 3.x MB?

Comment 12 Stephan Kulow 2007-09-06 12:38:14 UTC

... other way than to use nm

Comment 13 Dirk Mueller 2007-09-06 12:53:27 UTC

nm is linked against libbfd, which is the biggest part of the whole rpm. 

as far as I can see is it tries to extract the kabi version the module was compiled against. 

can't this be queried from modinfo or added there? I don't quite understand what the whole thing is good for, so I don't have a good solution to propose.

Comment 14 Stefan Dirsch 2007-09-06 13:00:13 UTC

I tried to explain it in my first comment. weak-modules makes sure that kABI compatible kernel modules of kmp packages are symlinked, so that they are still found by the update kernel. IIRC weak-modules has been written by agruen and is an important part of our KMP mechanism. I hope you won't kill it for openSUSE just to save some space on the CDs. Adding Susanne.

Comment 15 Stephan Kulow 2007-09-06 13:14:20 UTC

Surely not. It wouldn't be the first place where nm is used because it is so short in name :)

Comment 16 Andreas Gruenbacher 2007-09-06 17:10:30 UTC

Comment 10: It wouldn't be all that hard to parse the information out of the .ko files directly in module-init-tools. I'm rather unconvinced that the space savings justify the half day or so of development + testing though. If anyone considers this a significant enough problem, please pick it up with Michal. (For 10.3 it seems a bit late to me now anyway.)
