We had this situation before for a while. It has the substantial downside that e.g. you cannot do any system-wide systemtap tracing without making all strace and gdb use impossible. > Assuming the above is a semi-reasonable idea, it might be a lot less > work than updating the ptrace-via-utrace code to handle the new ptrace > changes. That's for Oleg to say. (Sorry, Oleg. ;-) Thanks, Roland
