Continuing the discussion from Bumping glibc requirements for the Rust toolchain:
Over 2 years ago, in the thread above, we were considering updating the Rust distribution builders from a CentOS 5 image to a CentOS 6 image. With the way glibc symbol versioning works, this would raise the minimum system level that can use the resulting binaries. This would only affect
linux-gnu architectures already use newer baselines.
From my position at Red Hat, I'll point to the life-cycle dates -- note that RHEL 5 was retired on March 31, 2017. It continues now in extended support, only fixing critical security issues and the most urgent bugs. CentOS 5 followed suit and is now only available in the archives, with no updates at all.
Does anyone else have concerns about raising to a ~RHEL/CentOS 6 equivalent of glibc 2.12?
cc @alexcrichton -- we talked about this a little at RustConf.
PS: Due to build requirements explained here, I would still like RHEL 5 kernel support for now.
