Any version of pip older than that and we don’t have insight into what they are (we can get kernel version if they’re using pip >= 1.4) and any installer other than that we don’t get any insight into either.
Is the kernel version table you mentioned trivial to get? I bet it's very closely correlated with glibc version. > One problem of course is deciding how representative only people who are using pip >= 6.0 is, though since we can’t get manylinux support into already released versions of pip it may be pretty representative of people who will use this feature (unless this feature causes people to upgrade their pip when they wouldn’t otherwise). > > Anyways, here’s the data: https://gist.github.com/dstufft/e1b1fbebb3482362198f One short summary: "wow, there are a ton of Debian 6 users out there". Esp. considering that even Debian unstable isn't shipping pip 6.0 yet. (Or who knows, I guess that could just be one very heavy user.) > It doesn’t matter to me if we use CentOS5 or CentOS6 as our base, but having some information to inform our choices is never a bad thing!
