Hi,

varnishd -V
varnishd (varnish-2.1.2 SVN ) (debian squeeze)

DAEMON_OPTS="-a :8081 \
             -T 127.0.0.1:6082 \
             -f /etc/varnish/default.vcl \
             -w 100,2000 \
             -s persistent,/var/lib/varnish/$INSTANCE/varnish_storage.bin,1G"

stop & start:
varnishadm -S /etc/varnish/secret -T 127.0.0.1:6082 stop
varnishadm -S /etc/varnish/secret -T 127.0.0.1:6082 start

and it seems that it works.

If I use /etc/init.d/varnish stop it doesn't work (it uses start-stop-daemon)
