Howto create openSUSE custom rootfs.
Based on this guide [https://en.opensuse.org/HCL:Chroot Chroot / do-it-yourself environment]

----

== DIY Enviroment ==

* First, download the latest JeOS, XFCE or E17 root file system (*armv7-rootfs*) available at:
[[@http://download.opensuse.org/ports/armv7hl/factory/images/]]
for example this one ''openSUSE-Factory-ARM-E17.armv7-rootfs.armv7l-1.12.1-Build172.10.tbz''

* Create type gpt partition table on mmc SD card or USB flash (i will use SD)
** Create two primary partitions, for example first '''lxboot''' and second '''lxroot'''
*** It is possible to put everything on one partition
** Format them to ext4

* Mount '''/lxroot''' to '''/mnt/temp''' and run
<pre>
sudo tar xvjf openSUSE-Factory-ARM-E17.armv7-rootfs.armv7l-1.12.1-Build172.10.tbz -C /mnt/temp
</pre>

* Create folders '''/boot''' and '''/dtb''' on '''lxboot''' partition

* Compile kernel 3.15-rcX using tegra_defconfig or custom config
** Copy resulting '''arch/arm/boot/zImage''' to '''lxboot/boot'''
** Copy resulting '''arch/arm/boot/dts/tegra20-paz00.dtb''' to '''lxboot/dtb'''
** Run make modules_install with INSTALL_MOD_PATH variable to some folder then copy resulting modules directories to '''lxroot/lib/modules/3.15-rcX-kernelname'''

* WIP Use precompiled kernel
** Self compiled kernel and modules https://dl.dropboxusercontent.com/u/32472722/opensuse/kernel-3.15.0-rc7-tegra.tar.gz
** Will add as rpm later

* Create boot.scr file
** boot.scr content example openSUSE style

** Copy resulting '''boot.scr''' to '''lxboot/'''

* <span style="color: #1d934c;">Now it is ready to run on AC100</span>

== Firstboot notes ==

* Howto install '''opentegra''' (<span style="color: #e51b3f;">your kernel must be 3.15-rc3 minimum</span>)
** Add AC100 specific repositories
<pre>
sudo zypper ar http://download.opensuse.org/repositories/X11:/XOrg/openSUSE_Factory_ARM/ openSUSE_Factory_ARM_X11_XOrg
sudo zypper ar http://download.opensuse.org/repositories/devel:/ARM:/Factory:/Contrib:/Tegra/standard/ devel_ARM_Factory_Contrib_Tegra_standard
</pre>

** Install latest XOrg version
<pre>
sudo zypper dup --from openSUSE_Factory_ARM_X11_XOrg
</pre>

** Install libdrm and xf86-video-opentegra packages
<pre>
sudo zypper in xf86-video-opentegra libdrm_tegra0 libkms1
</pre>

** opentegra xorg config live here '''/usr/share/X11/xorg.conf.d/opentegra.conf'''
*** You may need to remove this file if XOrg version can't parse its OutputClass section and create '''/etc/X11/xorg.conf.d/00-opentegra.conf''' config file
<pre>
Section "Device"
Identifier "opentegra"
Driver "opentegra"
EndSection
</pre>

* Fix permissions, if XOrg not suid by chance
<pre>
sudo zypper in --force permissions
</pre>
''' Not sure yet if this is correct fix
** If XOrg fail to start with some permission denied or existing file not found chmod it with suid rights manualy
<pre>
sudo chmod u+s /usr/bin/Xorg
</pre>

== U-Boot notes ==

* Load boot.scr manualy if you stuck in u-boot console
<pre>
ext2load mmc 1:2 0x10000000 /boot.scr
source 0x10000000
</pre>
