6 | # It's simple enough to figure out how this works. | |
7 | # If not, then you can ask me at stripconfig@goodmis.org | |
8 | # | |
9 | # What it does? | |
10 | # | |
11 | # If you have installed a Linux kernel from a distribution | |
12 | # that turns on way too many modules than you need, and | |
13 | # you only want the modules you use, then this program | |
14 | # is perfect for you. | |
15 | # | |
16 | # It gives you the ability to turn off all the modules that are | |
17 | # not loaded on your system. | |
18 | # | |
19 | # Howto: | |
20 | # | |
21 | # 1. Boot up the kernel that you want to stream line the config on. | |
22 | # 2. Change directory to the directory holding the source of the | |
23 | # kernel that you just booted. | |
24 | # 3. Copy the configuraton file to this directory as .config | |
25 | # 4. Have all your devices that you need modules for connected and | |
26 | # operational (make sure that their corresponding modules are loaded) | |
27 | # 5. Run this script redirecting the output to some other file | |
28 | # like config_strip. | |
29 | # 6. Back up your old config (if you want too). | |
30 | # 7. copy the config_strip file to .config | |
31 | # 8. Run "make oldconfig" | |
32 | # | |
33 | # Now your kernel is ready to be built with only the modules that | |
34 | # are loaded. | |
35 | # | |
36 | # Here's what I did with my Debian distribution. | |
37 | # | |
38 | # cd /usr/src/linux-2.6.10 | |
39 | # cp /boot/config-2.6.10-1-686-smp .config | |
40 | # ~/bin/streamline_config > config_strip | |
41 | # mv .config config_sav | |
42 | # mv config_strip .config | |
43 | # make oldconfig | |
44 | # | |
