Description of problem:
The tvtime binary is installed setuid root. Is that wise ?

AFAIK it is because it needs access to /dev/rtc

Can that not be solved in some other way ?

The last thing we need is a remote break-in over TV signals ;-)

Is there really no other way for precise timing but /dev/rtc ?

Version-Release number of selected component (if applicable):

Comment 1 Ngo Than 2004-11-16 16:14:03 UTC
yes, it's needed to set the max-user-freq on /dev/rtc. But I don't see
it's critical because it will be dropped to a user after doing that.

Comment 2 Ngo Than 2004-11-16 16:55:15 UTC
in my opinion it's safe by removing setuid root. I will remove it in
next rebuild. Perhaps adding "dev.rtc.max-user-freq = 1024" in
