Comment # 4 on bug 1226460 from Matthias Gerstner

It seems to be all right after all. The default setting of the YAMA security
module for ptrace_scope is 1, and always has been. Thus dropping the sysctl
file from aaa_base is okay, and only installing the new sub-package will
change the scope to 0. This detail was not clear to me from looking at the
commit that changed this.

I will initiate the process for adjusting the whitelistings.
