Hello Kees,

first of all, I'm so glad to finally see the /tmp/ and hardlink races
being addressed. And it only took like 10 years for the Linux world to
accept them :-)

This would be too unexpected and surprising IMHO. I'd rather ship a
file 10-ptrace-security.conf by default with the re-enabling sysctl
commented out, so that it's easy to re-enable without looking for
docs.

Thanks,

Martin
