A DYama.rst26 exist and remain possible if ptrace is allowed to operate as before.
27 Since ptrace is not commonly used by non-developers and non-admins, system
31 specifically disallow such ptrace attachment (e.g. ssh-agent), but many
32 do not. A more general solution is to only allow ptrace directly from a
44 to ptrace each other. If a process wishes to entirely disable these ptrace

58 1 - restricted ptrace:
