Yes, I know, but block device operations should, and directly feeding data
into /dev/*random, as I did, definitely should.
This machine usually has only very limited entropy available, but the pool
currently seeems to bee stuck at "0" - there's no way to get it to even
display a slightly different number. That's what confused me pretty much...
Normally doing disk IO helps a bit, but it currently does not at all.

I guess I also should do that - as this machine has several network cards on
different networks, that will be definiteely more seecure than running with
a completely empty entropy pool stuck at zero bits for several days in a
row...
