I am looking to speed up the boot time on my Raspberry pi and `systemd-random-seed` is taking 20s (old Pi 1). From what I've read up this is waiting to collect entropy to generate a system random seed. I don't care whatsoever about security and I'm wondering if there is some way to hard-code this, disable it, or otherwise make it not take so ridiculously long to boot?

I tried just running `systemctl disable systemd-random-seed` to see what would happen and it still ran at boot, so evidently it's being started by another service or something.

I'm completely new to Linux and raspberry if that wasn't already obvious, so sorry if it's a dumb question a requires a dumb answer... I attempted to look through the man page and it's completely over my head (wasn't sure how to translate that into the boot process).
