Dear all,
does anyone know how to extract the .config file from a compressed kernel image?
Best regards,
Promy |

Black magic and sorcery.
Okay, maybe not. Do this:
| Code: | # mkdir ~/configextractor
# cd ~/configextractor
# wget http://hypermail.idiosynkrasia.net/linux-kernel/archived/2002/week10/att-1489/01-binoffset.c -O binoffset.c
# gcc binoffset.c -o /usr/bin/binoffset
# cp /usr/src/linux/scripts/extract-ikconfig /usr/bin/
# chmod 755 /usr/bin/extract-ikconfig
# cd
# rm -r configextractor |
That downloads, compiles, and installs the required utility (binoffset) as well as installs extract-ikconfig. Now, just "extract-ikconfig /boot/bzImage" and you'll find the config in /boot/bzImage.oldconfig.somenumber.

I don't have this script. I'm using vanilla-sources. Is this only in the gentoo-sources or? |

Embedding the config file is a separate patch that is included only in gentoo-sources. It has to be enabled in the kernel configuration, as well.
