-  * On Linux systems TRandom reads from /dev/urandom.
+  * On Linux systems TRandom uses SYS_getrandom.
   * On Windows systems TRandom uses Windows built in [CryptGenRandom](https://msdn.microsoft.com/en-us/library/windows/desktop/aa379942(v=vs.85).aspx "CryptGenRandom") function.
   * On BSD systems TRandom uses [arc4random_buf](https://www.freebsd.org/cgi/man.cgi?query=arc4random_buf&sektion=3 "arc4random_buf") this is the same on Mac systems, because Mac = FreeBSD).
 
-TRandom will fall back on Free Pascal's [Random](http://www.freepascal.org/docs-html/rtl/system/random.html "Random") function which uses the [Mersenne Twister](https://en.wikipedia.org/wiki/Mersenne_Twister "Mersenne Twister") algorithm to get random bytes.
+TRandom will fall back on reading from /dev/urandom, then /dev/random, and finally Free Pascal's [Random](http://www.freepascal.org/docs-html/rtl/system/random.html "Random") function which uses the [Mersenne Twister](https://en.wikipedia.org/wiki/Mersenne_Twister "Mersenne Twister") algorithm to get random bytes.
