4Subject: [PATCH] Entropy seed for CzechLight
5
6Everything changed in sytemd v243 which gained a native service which is
7nowadays capable of crediting the seed with sufficient entropy. However,
8everything is still wrapped behind a random env variable (to guard
9against people cloning images) and runs rather late in the boot. The
10docs still suggest to run something custom "from the boot loader" on
11embedded systems with no HW random generator (hi ClearFog).
12
13So, given that we're using the pre-init shell script for seeding the
14random generator from disk, we only need this one for systemd to *save*
15the seed for the next boot.
