Let's download a raw SD images from a stable Debian distribution.
Check the page : http://elinux.org/BeagleBoardDebian#BeagleBone.2FBeagleBone_Black
Download the img file
wget https://rcn-ee.com/rootfs/2015-07-08/microsd/bone-debian-8.1-console-armhf-2015-07-08-2gb.img.xz
Check the downloaded file with md5 checksum tool:
md5sum bone-debian-8.1-console-armhf-2015-07-08-2gb.img.xz 24c9cba824396b44f2f8edcd3e7b94bb bone-debian-8.1-console-armhf-2015-07-08-2gb.img.xz
Copy the RAW SD image file on your Micro SDcard. You should check your "dmesg" or dev to determine where your Micro SDcard has been mapped.
unxz bone-debian-8.1-console-armhf-2015-07-08-2gb.img.xz sudo dd if=./bone-debian-8.1-console-armhf-2015-07-08-2gb.img of=/dev/sdX
You're done now!
Emacs, Git
You should have a look to the following page: http://pkg.jenkins-ci.org/debian
Type the following command-line to add the APT Key from Jenkins Package Server.
wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -
THis will return an "OK" message if it succeeded.
Then, add the following line in your /etc/apt/sources.list
deb http://pkg.jenkins-ci.org/debian binary/
Finally run the two last commands:
sudo apt-get update sudo apt-get install jenkins
The last command line will install Jenkins and all its dependencies. This could be quite heavy on a 2Gb card.
You're done now with Jenkins!
