Er, s/say/mean to imply/
I do think it will have some local value after Android 8 which should
start shipping in a few days though.
I'll look into having the kernel stash some entropy in pstore soon since
that seems like it could be a great improvement. I'm not sure how often
/ where it should hook into for regularly refreshing it though. Doing it
only on powering down isn't ideal.
