In the course of developing netboot menus, and rebooting my virtual machine often, I am running into a problem where Grub is reusing the same TCP client ports across reboots, and my server (because of TCP TIME_WAIT) objects to this.
I have a small change to set the initial client port based on grub_rtc_get_time_ms(), but I'm not sure if that functionality is available on all supported platforms. I'd like to provide a general contribution that works on all platforms. Is there a general way to get a pseudo-random integer that is different on each boot? Thank you very much!
