`generate-config.pl' runs `make config' to generate a Linux kernel configuration file. For each question (i.e. kernel configuration option), unless an override is provided, it answers "m" if possible, and otherwise uses the default answer (as determined by the default config for the architecture). This is safer than allmodconfig, which answers "y" everywhere it can't answer "m" and thus ends up enabling a lot of experimental or debug options. (For this reason, a configuration generated by allmodconfig must be carefully checked with every new release to ensure that nothing dangerous is enabled. The default config should be safer wrt new kernel releases.) Overrides are specified in the `config' argument to generic.nix, which is a string that contains lines such as `EXT2_FS_POSIX_ACL y'. The script warns about ignored options, and aborts if `make config' selects an answer inconsistent with the one in `config'. This allows us to be sure that `make config' doesn't silently override our configuration values (e.g., depending on other options, it will set FB_TILEBLITTING to "y" even if we want it to be "n"). svn path=/nixpkgs/branches/kernel-config/; revision=18910 |
