A better solution would be to not attempt to save and restore a seed
value that is intended to persist across reboots when it's on a tmpfs.
Putting the urandom seed into tmpfs is just a waste of time.
I have to wonder why we don't put a union mount tmpfs over /var/lib to
be honest...
or if we don't want to depend on unionfs, a tmpfs over /var/lib...

A union mount tmpfs over /var/lib (and maybe /etc) was the first
solution that came into my mind. Then I saw a bug related to unionfs
about getcwd() call, and I saw the unionfs was still disabled for live
images. So I thought "maybe I should not use unionfs".
A tmpfs over /var/lib.
Hmm... I thought about that too. The reason that I didn't use this
method was that I thought that some directories under /etc might also
need to be written to.
It turns out that this concern seems unnecessary.
Anyway, I'll try out the tmpfs-over-var-lib method and let you know the
result.
Thanks,
Chen Qi
