Re: [yast-devel] YaST installer - the future development (for 13.2/SLE12, aka "the new installer") - more details

Hello,

On Oct 16 16:58 Ladislav Slezak wrote (excerpt):
So here we go: https://github.com/yast/yast-installation/wiki/New-Installer

https://github.com/yast/yast-installation/wiki/New-Installer%3A-SLE12-Installer-Workflow
therein in section "3. Deployment (step 7 above) (ยง5)" reads:
-------------------------------------------------------------------------
o Create filesystem, optionally untar pre-installed images, install RPMs.
The images here are tar.xz images with pre-installed RPMs as are
currently used in openSUSE.

For SLE the image functionality will be probably not needed...
-------------------------------------------------------------------------

I disagree that "for SLE the image functionality is not needed".

In particular for SLE it is needed that after a system disaster
the new installer can re-create the system on new (compatible)
replacement hardware as it was before by using a saved config
of the system and deploying one or more backup.tar.gz images
that contain the files of the system.

To support this the new installer has to do those steps:
1. Boot New Machine
2. Use given config (i.e. the saved system config)
3. Disk Activation (e.g. special stuff to make SAN accessible)
4. Storage/Partitioning
5. Create filesystems and mount them at the right mount points
6. Deploy the files (i.e. untar backup.tar.gz images)
7. Install bootloader
8. Reboot

Ideally "Deploy the files" should support any mixture of
installing RPMs and whatever kind of software packages
plus untar backup.tar.gz images so that it would be possible
to have only user data in backup.tar.gz but use RPMs for
the basic system software and whatever kind of software
packages for other software like third-party software.

Is it planned that such system recovery/restore functionality
will be supported by the new installer in particular for SLE?


Kind Regards
