Upstart

Here I'm just listing some upstart scripts I've written to manage tasks not assumed by default configuration

iptables

I dont want to use some weird bloatware just to install couple of rules I need to protect my machine. So here we go...

/etc/init/iptables.conf:
description "Starts and stops firewall by restoring ip[6]tables policies.
 Save rules with iptables-save > /etc/default/iptables 
 and ip6tables-save > /etc/default/ip6tables"
author "Ruslan N. Marchenko <me(o)ruff.mobi>"

start on runlevel [2345] or net-device-up IFACE!=lo
stop on runlevel [!2345]
emits firewall

#task
console output

pre-start script
test -f /etc/default/iptables && /sbin/iptables-restore < /etc/default/iptables
test -f /etc/default/ip6tables && /sbin/ip6tables-restore < /etc/default/ip6tables
end script

post-stop script
/etc/default/iptables -F
/etc/default/ip6tables -F
end script

vgaswitcheroo

This nice pice of kernel code from Dave Airlie enables us to manage switchable graphic (optimus in NVidia world). This upstart script will just switch off discrete graphic card on startup and turn it on before shutting down (otherwise kernel is not quite happy while de-initializing kms)

/etc/init/radeon.conf:
description "Workaround for ATi Mobility Radeon card, switches off discrete card
 using vgaswitcheroo"
author "Ruslan N. Marchenko <me(o)ruff.mobi>"

start on virtual-filesystems
stop on runlevel [!2345]

pre-start exec modprobe radeon
post-start script
    echo -en "Switching off discrete VGA card."
    until grep Off /sys/kernel/debug/vgaswitcheroo/switch
    do
        sleep 1
        echo OFF > /sys/kernel/debug/vgaswitcheroo/switch
        echo -en "."
    done
    echo " Done"
end script

post-stop script
    echo ON > /sys/kernel/debug/vgaswitcheroo/switch
end script
