truss output for freac

There is no dmesg output related to freac

I suppose, the relevant truss output lines are

fstatat(AT_FDCWD,"/dev/cd0",{ mode=crw-rw---- ,inode=108,size=0,blksize=4096
},0
x0) = 0 (0x0)
readlink("/dev/cd0",0x7fffffffbd80,255)          ERR#22 'Invalid argument'
fstatat(AT_FDCWD,"/dev/cd0",{ mode=crw-rw---- ,inode=108,size=0,blksize=4096
},0
x0) = 0 (0x0)
nanosleep({ 0.100000000 })                       = 0 (0x0)
openat(AT_FDCWD,"/dev/cd0",O_RDONLY,00)          = 11 (0xb)
ioctl(11,CDIOCALLOW,0x0)                         = 0 (0x0)
ioctl(11,0xc4e01903 { IORW 0x19('?'), 3, 1248 },0x805156608) ERR#25

++ WARN: open: Inappropriate ioctl for device
write(1,"++ WARN: open: Inappropriate ioc"...,46) = 46 (0x2e)
close(11)                                        = 0 (0x0)

complete truss output attached

It doesn't matter whether a cd is inserted or not, the error is always thrown.
