That's a 4096-bit safety net (uncredited entropy) which at least Debian shall not remove. I think Debian also dumps some low-entropy-per-bit crap into /dev/random during boot (again, not credited), such as the boot kernel logs. We could increase the density of that entropy a lot using gzip -0 or something like that... is an uncredited low-entropy-per-bit dump into the pool detrimental to its quality? -- "One disk to rule them all, One disk to find them.
