Find out the current kernel config settings?
 

If I'm on a linux system (Any linux e.g. Fedora, SLES, Ubuntu)

Can I find out the current kernel config settings?
How do I do this?
Is there a .config file that stores these?

Have a look in the /boot directory. Look for a file with config in its name.

Examples:
- on a Debian 6 box: config-2.6.32-5-amd64
- on a rhel 6 box: config-2.6.32-220.el6.x86_64

Alternatively, you can on most kernels find the current config as a compressed file at /proc/config.gz.

@TobiSGD: The option to do this (CONFIG_IKCONFIG) isn't enabled by default.

Debian (6+7) and RHEL (5+6) don't make use of this out-of-the-box.

I was able to do this:
zcat /proc/config.gz >my_config

and then look at the config file.

Thanks
