Probably most of your question about Fedora 9 are answered there and
the solutions are simple.
Whoever added the setuid cdrecord stuff for k3b, please delete that
or at least give the rationale for making the tools +s. k3b's warning
can't be the only reason.
Just a clarification, I cdrecord is not installed on FC9 at all, rather
there is a program called "wodim" which is linked to cdrecord. Wodim is
a modified version of an old version of cdrecord, not the current
program from the original author.
By any name the kernel filters commands send to the burner which
prevents certain commands from being sent unless you are root,
particularly commands specific to a particular vendor. The author of the
original and still maintained cdrecord program asked that the command
filtering be changed, but the kernel maintainers declined. The author of
cdrecord was invited to learn to use capabilities rather than root, and
*he* declined. As you might guess, there are personalities and politics
involved, and the result is that cdrecord needs to run as setuid root.
Since Fedora is usually pretty cutting edge, it would be nice if wodim
were called that, and only that, and since a setuid program is being
run, why not the real cdrecord? I suspect there are politics involved
there as well. It's disappointing that Fedora didn't change to using
capabilities, although that may be harder than it seems.
In any case, there's the overview and the technical issue, you need
privileged commands to burn on some hardware, and there are some monster
egos in play. Perhaps someone will comment on why not real cdrecord and
capabilities.
