I'll maybe tackle it after I'm done the work on configs and USE=modules.

The only time I'm saying that uname -r and /proc/config.gz are looked as, is where there is no kernel sources or they are installed but not configured. But that is as part of a larger body of work to fix up all packages that are merely checking the kernel options during build, not relying on the config to build. Kernel modules still require configured sources to be installed. > Thanks for working on this. It's a sensitive area so please take > care and help people pick up the pieces.

For anybody following this, we're doing the work on two tracker bugs: 283320 - Changes to linux-info 283900 - USE=modules change for linux-mod and packages. We've got the core eclass stuff done, but not enabled yet. If you want to test it it: 1. mv your .config or entire kernel sources away 2. I_KNOW_WHAT_I_AM_DOING=1 emerge udev You should get warnings, but no errors. -- Robin Hugh Johnson Gentoo Linux: Developer, Trustee & Infrastructure Lead E-Mail : robb...@gentoo.org GnuPG FP : 11AC BA4F 4778 E3F6 E4ED F38E B27B 944E 3488 4E85
