Implementations don't seem the same?
- Linux seems to try kernel then falls back to generating an own using
- Solaris, FreeBSD4 and Darwin always use urandom.
- FreeBSD5 uses syscall or libc function depending on FPC_USE_LIBC
I assume Solaris/Darwin could attempt kernel generation too (depending on
major OS version maybe, like FreeBSD), Linux is missing libc implementation
and always does an own thing bypassing system libs.
