cdrecord warning message

[Rick Pasotto]

I recently rebuilt my system. I didn't use to get this message:

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.

The cd burned just fine but I'd like to know what needs to be changed to
avoid the warnings. I'm burning it as a regular user that's been added
to the cdrom group.

BTW, is there a way to re-read the /etc/group file without logging out
and then logging in?

Simply that cdrecord wants to do things that root is allowed, but a normal
user is not.

Which gives you access to the device, but doesn't give you access to
setpriority().

Either run cdrecord as root (using sudo, for instance), or set it suid
root, so that it can do what it wants to do.

No. Or not really. What's wrong with logging in again?

Will work with SUID only with the latest Sid version.
