I can't speak for cdrecord, but cdrdao gives up its root privileges 
after setting its burn thread priority.

Also a word of warning: there might be cdrdao regressions in F-7 because 
cdrdao has to link with an older unpatched version of the cdrtools 
library (that's shipped with cdrdao), since F-7 dropped cdrtools in 
favor of cdrkit. I have plans to work on porting cdrdao to cdrkit (or 
libburnia), but it might take a while... People willing to help should 
contact me directly.
