Baselayout-2 / udev wants the kernel config -- FIXED
I am just starting here, trying to set up a gentoo image. I updated the profile and am trying to remerge system, and world, but first I want to upgrade to baselayout-2.
The problem is udev wants the kernel config. It is looking in /usr/src/linux, which emerge populated with linux-2.6.31-r6. That's nice, but I haven't built a kernel because it boots off the Linode kernel, and I don't want to make up my own config which is unrelated to what actually boots.
First off, this sounds silly, but do I need udev on a Linode image? I suspect so, but I figure I meed to confirm that.
One way to get udev to merge would be to get the config used by the Linode booting kernel (22.214.171.124-x86_64-linode9). Is this available? I don't mind stuffing it into /usr/src/linux and building a kernel to fool udev.
Are there other ways to fool udev, or is there a better solution doing something entirely different?
Alternatively, if it's a 2.6 kernel, /proc/config.gz should provide you with the active configuration, though whether or not that's sufficient for a particular application or tool chain would depend on the specific tool at hand.

Other than fiddling with the ebuild itself as a temporary hack, is there some way to get around this?
The bug you posted regarding SOCK_CLOEXEC was fixed in around 2.6.28… and the error you posted suggests ebuild thought it had detected an older-than-2.6.25 kernel version in /usr/src/linux.
In a pinch, you could apply a trivial custom modification to the kernel sources if you wish, to assist in getting past that barrier:
Apologies for borking it and asking for help. I ought to know better by now!
