Hello.

I've tried to update cdrtools... To find out that they are not fully 
functional.

$ cat /etc/security/exec_attr.d/cdrtools
Basic Solaris 
User:solaris:cmd:RO::/usr/bin/cdrecord:privs=file_dac_read,sys_devices,proc_lock_memory,proc_priocntl,net_privaddr
Basic Solaris 
User:solaris:cmd:RO::/usr/bin/readcd:privs=file_dac_read,sys_devices,net_privaddr
Basic Solaris 
User:solaris:cmd:RO::/usr/bin/cdda2wav:privs=file_dac_read,sys_devices,proc_priocntl,net_privaddr

When I try to blank cd-rw device, I get with new cdrtools :

$ cdrecord blank=all

'cdrecord -v blank=fast' doesn't give this error.

Do I miss some privileges?
