Neither will block, because we explicitly mark /dev/random as seeded with a SYSINIT late in the boot (not as late as I'd like, but not too early either). > I think DES's patch will help there too (not that anyone testing our > ZFS patches reported any hangs... including when testing GELI -- this > was before DES's patch). If you mean the device attach entropy gathering, that was a case of parallel invention from Pawel and myself, where I ended up using Pawel's patch with minor modifications.
