As of now, use 'copytruncate' because sheepdog is going to handle HUP
it's own way.
The risk of loosing a bit of the log during the rotation I think is irrelevant.
I sent a patch to remove sheepdog log rotation but it will affect
0.9.1 and not 0.9.0.

The easy way is to start sheep with '--pidfile /var/run/sheep.pid' and
I recommend that.
By the way, from my tests this works as well
kill -HUP $(/usr/bin/pgrep -x sheep | head -1)
for 0.9.0, use copytruncate
for 0.9.1, if my patch is correct, better use kill -HUP $(cat
please add --pidfile option alreay in 0.9.0 package.
