me neither
The first one I get, is the "sysctl" one. It is produced during the
/etc/rc.d/sysdb script, probably by the dev_mkdb program (which uses cdb,
probably using arc4random which uses sysctl to load random data?)
Since I have not updated my boot.cfg but random_seed=YES in the
/etc/defaults/rc.conf file, I guess the entropy file *is* being loaded,
but after it is required..

The second one I get is the "kernel" one, and this is produced during a
fetchmail run after I have logged in. I don't know why that would use
kernel entropy.. perhaps picking a random port number? Also, that is
*after* the entropy file was loaded.. is that not enough for the kernel?
