The default i/o scheduler is the Completely Fair Queuing (cfq) in the 2.6 kernel. This is not the first choice for a virtual machine/hypervisor. The combination of the noop and the deadline scheduler is much better for a virtualization host.

#!/sbin/runscript
depend() {
use logger dns
need apache2
provide jenkins

JENKINS_USER=jenkins
LOCKFILE=/var/run/jenkins.pid

CONFIG_NETFILTER_ADVANCED
CONFIG_BRIDGE_NF_EBTABLES
