That sounds like the problem, although logging in to Gnome as
root didn't make any difference. A truss of my gnome-terminal shell
as root while it invoked the rhythmbox command as an ordinary
user revealed the problem. A couple of times when it executed
cdda2wav, it got return code 7, which means `pipe communication
errors encountered (in forked mode)'. The cdda2wav command is
a shell script that runs pfexec. This command is setuid root, but when
it executed cdda2wav.bin, the UID was my own, not zero. Before
that, it set them to my UID thusly:
6750: setppriv(PRIV_ON, PRIV_INHERITABLE, {002000080201000000000000}) = 0
6750: setreuid(107, 107) = 0
6750: getppriv(PRIV_INHERITABLE, {002200087301000000000000}) = 0
6750: setppriv(PRIV_SET, PRIV_PERMITTED, {002200087301000000000000}) Err#1
EPERM
I see from /etc/security/exec_attr that the necessary privilege is
`sys_devices'. When I run `ppriv -v $$', I only see that privilege
listed under `L'. Once I figure out how to change that, I'll try again.
