it seems that anaconda does the job and create the checksum and the sha1 automatically

==> in fact this is handled by the build_iso script [[User:Unnilennium|Unnilennium]] ([[User talk:Unnilennium|talk]]) 16:23, 17 July 2016 (CEST)

===Foreword===
 +
Red Hat suggest to create a product.img (https://access.redhat.com/documentation/en/red-hat-enterprise-linux/7/anaconda-customization-guide/2-working-with-iso-images#sect-product-img) and to put it in the folder images at the root of the CD, however, Centos did not use this way, but rather edited directly the anaconda image inside the live image.
 +
 +
Also, we might want to patch Anaconda at least to handle the degraded raid 1
 +
 +
Hence I feel we will have to do the same to hide all Centos branding.[[User:Unnilennium|Unnilennium]] ([[User talk:Unnilennium|talk]]) 17:20, 17 July 2016 (CEST)
 +
 +
=== THE KEY===
 +
 +
- the holly Grail is the .buildstamp file
 +
$ cat product/.buildstamp
 +
 +
[Main]
 +
Product=Koozali SME Server
 +
Version=10alpha2

=== how to create a good product.img for SME 10 alpha 2  (WIP)===
 +
mkdir product
 +
cd product
 +
 +
create the followings directories
 +
mkdir -p ./run/install/product/pyanaconda/installclasses
 +
mkdir -p ./usr/lib64/python2.7/site-packages/pyanaconda/installclasses
 +
mkdir -p ./usr/share/anaconda
 +
mkdir -p ./usr/share/anaconda/pixmaps/rnotes/en
 +
mkdir -p ./usr/share/xml/scap/ssg/content
 +
mkdir -p ./usr/share/anaconda/help/en-US/CentOSPlaceholder.html
 +
mkdir ./etc
 +
 +
add following files and edit (I think only one of them would be useful):
 +
./run/install/product/pyanaconda/installclasses/custom.py
 +
./run/install/product/pyanaconda/installclasses/koozali.py
 +
 +
make a copy of the following from the original rootfs and edit in case to hide the centos one :
 +
./usr/lib64/python2.7/site-packages/pyanaconda/installclasses/centos.py
 +
 +
we can put one  here too  (I think only one of them would be useful):
 +
./usr/lib64/python2.7/site-packages/pyanaconda/installclasses/koozali.py
 +
 +
make a copy and edit the following from the original rootfs:
 +
./usr/share/anaconda/anaconda-gtk.css
 +
 +
put your own image there with he right format, and the following name to hide the original centos files (you can also add more)
 +
./usr/share/anaconda/pixmaps/rnotes/en/centos-artwork.png
 +
./usr/share/anaconda/pixmaps/rnotes/en/centos-cloud.png
 +
./usr/share/anaconda/pixmaps/rnotes/en/centos-core.png
 +
./usr/share/anaconda/pixmaps/rnotes/en/centos-jp.png
 +
./usr/share/anaconda/pixmaps/rnotes/en/centos-promotion.png
 +
./usr/share/anaconda/pixmaps/rnotes/en/centos-virtualization.png
 +
./usr/share/anaconda/pixmaps/sidebar-bg.png
 +
./usr/share/anaconda/pixmaps/sidebar-logo.png
 +
./usr/share/anaconda/pixmaps/topbar-bg.png
 +
 +
 +
there are a lot of centos reference there, maybe we want to do something with it:
 +
./usr/share/xml/scap/ssg/content/ssg-centos6-ds.xml
 +
./usr/share/xml/scap/ssg/content/ssg-centos7-ds.xml
 +
./usr/share/xml/scap/ssg/content/ssg-centos7-xccdf.xml
 +
./usr/share/xml/scap/ssg/content/ssg-firefox-ds.xml
 +
./usr/share/xml/scap/ssg/content/ssg-jre-ds.xml
 +
./usr/share/xml/scap/ssg/content/ssg-rhel7-cpe-dictionary.xml
 +
./usr/share/xml/scap/ssg/content/ssg-rhel7-cpe-oval.xml
 +
./usr/share/xml/scap/ssg/content/ssg-rhel7-oval.xml
 +
 +
and the branding of the os installer:
 +
./etc/centos-release
 +
./etc/os-release
 +
./etc/redhat-release
 +
./etc/e-smith-release
 +
./etc/system-release-cpe
 +
 +
edit the buildstamp accordingly
 +
./.buildstamp
 +
 +
do the following:
 +
find . | cpio -c -o | gzip -9cv > ../product.img; cd ..
 +
cp product.img /build/smeserver/stage/10/x86_64/images/
 +
 +
 +
TO DO :
 +
*translation files ?
 +
*CentOSPlaceholder.html
 +
*help files
 +
*/usr/share/centos-release/EULA
 +
 +
=== alternative how to edit content of squashfs for SME 10 alpha 2  (WIP)===
 +
 +
f we want a little more liberty in term of remove centos 7 branding in the installer (eg, remove pictures to use the name we want for ours instead of hiding centos ones):
 +
 +
* first extract the content of Live image, and the image of Anaconda inside
 +
cd /build/smeserver/stage/10.0.alpha1/x86_64/LiveOS/
 +
mkdir /mnt/squashfs
 +
sudo mount -o loop squashfs.img /mnt/squashfs
 +
mkdir -p  /tmp/rootfs/LiveOS
 +
cp -a /mnt/squashfs/LiveOS/rootfs.img /tmp/rootfs/LiveOS/
 +
mkdir /mnt/rootfs
 +
sudo umount /mnt/squashfs
 +
sudo mount -o loop /tmp/rootfs/LiveOS/rootfs.img /mnt/rootfs
 +
 +
 +
*then we have to modify what we want like usual
 +
 +
WORK IN PROGRESS:
 +
NB: cp and rm inside the fs will need to be done with sudo :(
 +
 +
# usr/share/anaconda/pixmaps/ content (logo, side bar, top bar, etc.)
 +
# usr/share/anaconda/pixmaps/rnotes/en/ content  (Banners for the installation progress screen)
 +
# usr/share/anaconda/anaconda-gtk.css (gui stylesheet)
 +
# run/install/product/pyanaconda/installclasses/custom.py (for changing the product name as told by red hat)
 +
# usr/lib64/python2.7/site-packages/pyanaconda/installclasses/centos.py ( to effectively change the product name!! )
 +
 +
we can also remove centos pictures in rnotes this way.
 +
 +
 +
* finally rebuild images
 +
sudo umount /mnt/rootfs
 +
rm /build/smeserver/stage/10.0.alpha1/x86_64/LiveOS/squashfs.img
 +
cd /build/smeserver/stage/10.0.alpha1/x86_64/LiveOS/
 +
mksquashfs /tmp/rootfs  squashfs.img
 +
 +
=== patch anaconda and rebuild the whole installer  for SME 10 alpha 3 or next  (WIP)===
