I would really like to see a patch applied to glibc that ensures that the =E2=80=9Cprlimit64=E2=80=9D syscall is not used when running on the RHE= L 6 kernel (2.6.32). The lack of this syscall on that kernel means that getrlimits fails, which makes it impossible to start the JVM. This problem appeared with the upgrade to glibc 2.26 already, and ever since I=E2=80=99ve been trying to minimize the damage for RHEL 6 systems wh= ere Guix is used as a package manager (such as the MDC). A work-around for glibc 2.27 that makes things work fine with the RHEL 6 kernel would be very welcome! I=E2=80=99ve started a branch =E2=80=9Crhel6= =E2=80=9D where the default glibc has been bumped back to version 2.25 but I really don=E2=80= =99t want it to be a long-lived branch; one of the reasons is that building all packages for this old glibc version (even just on x86_64) puts our build farms under extra stress that I would like to avoid. Another thing that could go in is the new Guile wrapper for wrapped scripts that I proposed a few months ago. It requires a change in build-side code to provide a =E2=80=9Cwrap-script=E2=80=9D procedure (it wo= uldn=E2=80=99t be used just yet). -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
