Disable service auto startIn order to make a service NOT start on boot, do one of the following...
If the service is Upstart based (check with "status varnish")
echo 'manual' > /etc/init/varnish.override
If not, use the old fashion update-rc.d method:
update-rc.d varnish disable

Reboot while file system is read-only
# reboot -f bash: /sbin/reboot: Input/output error
You get this if your file system had failed and goes into read-only mode.
You could try and remount it read/write but I think rebooting is better since a dirty file system will be checked in single user mode.
You can reboot forcefully like this:
echo 1 > /proc/sys/kernel/sysrq # Enable SysRq echo b > /proc/sysrq-trigger # Reboot with no questions asked!
