A bit off topic but i personally am still thinking, really, that
people would rather be reenabled to do what they did for long.

It is a young Linux distribution. Maybe they would consider to
use /dev/random instead of /dev/urandom, but fed in noise is fed
in noise in the end.
OpenBSD, just as an example, does in /etc/rc
# Push the old seed into the kernel, create a future seed and create a seed
# file for the boot-loader.
random_seed() {
dd if=/var/db/host.random of=/dev/random bs=65536 count=1 status=none
chmod 600 /var/db/host.random
dd if=/dev/random of=/var/db/host.random bs=65536 count=1 status=none
dd if=/dev/random of=/etc/random.seed bs=512 count=1 status=none
chmod 600 /etc/random.seed
}
Once i had to write entropy-saver.c (i later also had to install
haveged and this still do not understand why, rhetorically) it was
only to undo the mental displacement i encountered when the RNG no
longer became seeded upon system boot on my AlpineLinux VM,
resulting in boot hangs of up to half an hour (due to ssh iirc).
