В общем, такая вот проблемка... При попытке записать CD-R из-под юзера (5-я Федора), cdrecord даёт следующие предупреждения:
cdrecord: Cannot allocate memory. WARNING: Cannot do mlockall(2). cdrecord: WARNING: This causes a high risk for buffer underruns. 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.

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.
При попытке записать из-под k3b, запись через некоторое время прерывается, из консоли вроде как проходит нормально. Из-под root-а таких проблем нет. Попытка поставить suid на cdrecord, как здесь советовали, не помогла - выдаётся сообщение о временной недоступности устройства:
cdrecord: No write mode specified. cdrecord: Asuming -tao mode. cdrecord: Future versions of cdrecord may have different drive dependent defaults. cdrecord: Continuing in 5 seconds...
