Description Kamil Dudka 2017-07-21 12:19:42 UTC 
Description of problem:
mock can no longer be used to build Fedora rawhide packages on a RHEL-6 box
because glibc started to require a newer running kernel.  The required kernel
version is, however, not available for RHEL-6.


Version-Release number of selected component (if applicable):
glibc-2.25.90-27.fc27


Steps to Reproduce:
# yum install mock
# mock --yum --init -r fedora-rawhide-x86_64


Actual results:
[...]

Expected results:
Successfully initialized mock profile.

This is the expected behaviour. You need a Linux 3.2 or newer kernel to run glibc 2.25.90 (2.26 development series).

You can no longer build Fedora Rawhide packages on RHEL 6. Workarounds include booting a VM with a newer Linux kernel to build glibc. Alternatively you can upgrade to RHEL 7.

From the glibc NEWS:

Version 2.26

...

* The minimum Linux kernel version that this version of the GNU C Library
  can be used with on i[4567]86 and x86_64 is 3.2.  A Linux 3.2 or later
  kernel was already required on all other architectures.

Therefore this is CLOSED / NOTABUG.

Eventually upstream will remove the "FATAL: kernel to old" error message and allow individual syscalls to fail.
