Fix ignored mode of tmpfs mount on /tmp

Problem

A readonly raspberry pi with /tmp mounted in fstab as mode=1777 had mode 0755 after boot. This caused several programs such as dhcpcd not to work correctly.

The same issue is also desribed in http://superuser.com/questions/1103101/how-can-i-mount-a-tmpfs-to-tmp-via-fstab-writable-to-anyone and http://unix.stackexchange.com/questions/289377/fstab-doenst-read-mode-value

Inspired from https://blog.petrzemek.net/2014/03/23/restarting-a-python-script-within-itself/

def restart():
        import sys
        print("argv was",sys.argv)
        print("sys.executable was", sys.executable)
        print("restart now")

Docker Swarm Network Overlay DNS Resolv not working (Docker 1.11.1)

I was running a docker swarm network overlay. It was using the company internal dns to resolv (10.0.0.1)

I created the network using:

docker -H :4000 network create test

 docker -H :4000 network inspect test

How-to setup a simple git push deployment

These are my notes basically. At first i created this gist just as a reminder for myself. But feel free to use this for your project as a starting point. If you have questions you can find me on twitter @thomasf https://twitter.com/thomasf This is how i used it on a Debian Wheezy testing (https://www.debian.org/releases/testing/)

test if modeswitch works

$ sudo usb_modeswitch -v 0x12d1 -p 0x1f01 -M "55534243123456780000000000000a11062000000000000100000000000000"

if yes than usually you would do this (but for me it did not work)

#edit config file
/etc/usb_modeswitch.conf
