[Sisuite-devel] systemimager big progress.

[LAHAYE O. <oli...@ce...>]

Dear all,

systemimager is still progressing a lot.

1/ now, installscript is not responsible anymore to create the filesystems raids, lvm and such.
An simple autoinstallscript.conf file named <imagename|hostname|scriptname>.xml located in/var/lib/systemimager/disks-layouts/ will give description of what you want to the dracut logic.
This means that you can have a single image deployed to multiple nodes with different disks.

2/ now, installscript is not responsible anymore to install the image.
The logic is in dracut module.
The script is ran after disks are initialized but before image is laid down to disk.
then the post install scripts are ran.
This permit to mount some extra stufs for example that are not in disk layout xml file.
This main script will become optional.

Minimum requirement will be disk layout and image. Often post install will be used. Pre-install and main install will be used rarely IMHO.

/var/lib/systemimager will be lifted to be more clean.
It will become:
- /var/lib/systemimager/<something>/hosts
- /var/lib/systemimager/<something>/pre-install
- /var/lib/systemimager/<something>/main-install
- /var/lib/systemimager/<something>/post-install
- /var/lib/systemimager/<something>/disks-layouts

something is now called scripts, but it's more than that so it'll change for something more concistent.

Expect a working release in less than a month.
