Add tinyipa to IPA imagebuild directory
TinyCoreLinux is a small 10mb base linux distribution which can easily be built into a ramdisk for PXE and ISO booting. This patch adds scripts and other required files to build a TinyCore based ramdisk which runs the Ironic Python Agent. Change-Id: I79fbec75de19b3d6feb19f87a3a0f662eae42bf3

=============================
2+
Tiny Core Ironic Python Agent
3+
=============================
4+
5+
.. WARNING::
6+
This is experimental! Build tested on Ubuntu Server 14.04 and Debian Jessie
7+
8+
Build script requirements
9+
-------------------------
10+
For the main build script:
11+
12+
* wget
13+
* pip
14+
* unzip
15+
* sudo
16+
* awk
17+
18+
For building an ISO you'll also need:
19+
20+
* genisoimage
21+
22+
Instructions:
23+
-------------
24+
To create a new ramdisk, run::
25+
26+
make
27+
28+
or::
29+
30+
./build-tinyipa.sh && ./finalise-tinyipa.sh
31+
32+
This will create two new files once completed:
33+
34+
* tinyipa.vmlinuz
35+
* tinyipa.gz
36+
37+
These are your two files to upload to glance for use with Ironic.
38+
39+
Building an ISO from a previous make run:
40+
-----------------------------------------
41+
Once you've built tinyipa it is possible to pack it into an ISO if required. To
42+
create a bootable ISO, run::
43+
44+
make iso
45+
46+
or::
47+
48+
./build-iso.sh
49+
50+
This will create one new file once completed:
51+
52+
* tinyipa.iso
53+
54+
To build a fresh ramdisk and build an iso from it:
55+
--------------------------------------------------
56+
Run::
57+
58+
make all
59+
60+
To clean up the whole build environment run:
61+
--------------------------------------------
62+
Run::
63+
64+
make clean
65+
66+
For cleaning up just the iso or just the ramdisk build::
67+
68+
make clean_iso
69+
70+
or::
71+
72+
make clean_tinyipa
73+
74+
Advanced options
75+
----------------
76+
77+
If you want the build script to preinstall everything into the ramdisk,
78+
instead of loading some things at runtime (this results in a slightly bigger
79+
ramdisk), before running make or build-tinyipa.sh run::
80+
81+
export BUILD_AND_INSTALL_TINYIPA=true
