I have had this occuring to me at times over again.

When rebooting your newly compiled kernel or want to reboot with a different kernel, the /usr/src/linux link is pointing at that other kernel source tree.

That is bad when compiling nvidia kernels, glibc or what kernel-dependent you are emergeing. This is my solution to guarrantee this will never happend:

Code:
/etc/conf.d/local.start:
rm /usr/src/linux
ln -s /usr/src/linux-`uname -r`


This can ofcourse be modified to suit your gentoo-rX kernel with appropriate syntax for 'uname'.

Thought it could be handy.

Thats also probably just as handy with any other linux were you may have more than one set of kernel sources. Thanks for that tip.

[/code]

I think you can also set USE="symlink" and the link will automatically be updated when you emerge a new set of kernel sources.

well, the gentoo vanilla is also named differently which I am using in another machine. So I think you should be cool with uname syntaxes there too (not -r though, or?) I am not all sure here and am not an expert in filtering and uname:ing so I wont say it will work definitely. :)

Ah, didnt know that. Still, if you rely on kernels outside the emerge tree you can always use this one. Like me (kernel.org tree kernel)
