Description Dave Maley 2003-10-21 21:43:02 UTC

From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031014

Description of problem:
When using cdrecord as a normal user I see the following warning messages:

> cdrecord: Operation not permitted. WARNING: Cannot set RR-scheduler
> cdrecord: Permission denied. WARNING: Cannot set priority using setpriority().
> cdrecord: WARNING: This causes a high risk for buffer underruns.

I changed /usr/bin/cdrecord to suid root, as suggested in the man page:

     chown root /usr/bin/cdrecord
     chmod 4711 /usr/bin/cdrecord

... however this didn't help.

There don't seem to be any actually problems burning CD's as a normal user, just
the warning messages.  

These warnings are not present when using cdrecord as the root user.


Version-Release number of selected component (if applicable):
cdrecord-2.01-0.a19.1

How reproducible:
Always

Steps to Reproduce:
1. as normal user: cdrecord -v -dao -pad -eject <image.iso>
2.
3.
    

Actual Results:  CD burned fine, but warning messages are displayed

Expected Results:  no warnings

just warnings that it cannot get into the realtime scheduler... please report
this upstream to the author of cdrecord
