* PidRef conversion work:
- - pid_is_unwaited() → pidref_is_unwaited()
- - pid_is_alive() → pidref_is_alive()
- - is_kernel_thread() → pidref_is_kernel_thread()
- - pid_is_my_child() → pidref_is_my_child()
- - get_process_uid() → pidref_get_uid()
+ - cg_pid_get_xyz()
+ - pid_from_same_root_fs()
+ - get_ctty_devnr()
+ - mount_image_in_namespace()
+ - bind_mount_in_namespace()
+ - pid1: sd_notify() receiver should use SCM_PIDFD to authenticate client
- actually wait for POLLIN on pidref's pidfd in service logic
- - exec_spawn()
- - cg_pid_get_unit()
+ - exec_spawn() + safe_fork()
- openpt_allocate_in_namespace()
- sd_bus_creds
- unit_attach_pid_to_cgroup_via_bus()
