Description Nikoli 2013-10-23 03:45:34 UTC 
Enabled FEATURES='cgroup ipc-sandbox network-sandbox' and tried booting kernel with 'CONFIG_NAMESPACES is not set' and running emerge: instead of graceful warning it prints this message during every ebuild phase:
Unable to unshare: EINVAL

I think when any of FEATURES='cgroup ipc-sandbox network-sandbox' is enabled emerge should check during every start if these linux kernel features are available and working correctly, if they are not, emerge should print red warning and do not try to use them or better exit with error.

I agree that a more helpful error message would be great but I can't work on the patch right now. Sorry.
