I'd say the opposite. On a single-user system, using "/usr/src" to check out code or unpack a source-code tarball's OK if that's what you want to do but on a multi-user system, no way (even if this was SOP a century or two ago)! I've been pointed to this email of Linus's: https://lkml.org/lkml/2000/7/27/10 <begin> I would suggest that people who compile new kernels should: - NOT do so in /usr/src. Leave whatever kernel (probably only the header files) that the distribution came with there, but don't touch it. - compile the kernel in their own home directory, as their very own selves. No need to be root to compile the kernel. You need to be root to _install_ the kernel, but that's different. - not have a single symbolic link in sight (except the one that the kernel build itself sets up, namely the "linux/include/asm" symlink that is only used for the internal kernel compile itself) And yes, this is what I do. My /usr/src/linux still has the old 2.2.13 header files, even though I haven't run a 2.2.13 kernel in a _loong_ time. But those headers were what glibc was compiled against, so those headers are what matches the library object files. And this is actually what has been the suggested environment for at least the last five years. I don't know why the symlink business keeps on living on, like a bad zombie. Pretty much every distribution still has that broken symlink, and people still remember that the linux sources should go into "/usr/src/linux" even though that hasn't been true in a _loong_ time. Is there some documentation file that I've not updated and that people are slavishly following outdated information in? I don't read the documentation myself, so I'd never notice ;) </end> -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe". Trouble?
