[sles-beta] Suggestion to speed up installs/Upgrades/patching for "future" SLE

[Darren Thompson]

Team

Whilst watching an upgrade/install of SLE-12 I made the following
observation:
1. dracut takes a long time to build it's images and install.
2. dracut is called LOTS of times during the installation process (every
time a process touches a startup device etc, e.g. Kernel, multipath,
portland etc.
3. Logically only the 'last" time it's run is it doing anything useful.

My suggestion:
Analyse the installation process for modules that touch a startup device.
Set a "dracut needed" flag instead of actually running dracut
Get yast/zypper to check for the "dracut needed" flag and run it as the
last action during an install if set.

I know that probably requires touching some low level install processes but
I think the speed-up produced would make that worth investigation.

Regards
