[Systrace] How can a process check if it is running under systrace?

[Kevin]

I have a lot of programs that check the output of getuid() or
geteuid() to determine if they are running as root, and will not even
try to chroot() or do other privileged operations.

Is there any standard means (under OpenBSD) for a process to determine
whether it is running under systrace, short of just trying to do
operations (such as chroot) normally restricted only to root?


Thanks,
