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

[Matthias G. Eckermann]

Hello Darren,

don't you think that we already did consider this?

The problem with this approach is that it leaves the
system in an undefinied / inconsistent state for a few
minutes, and if it crashes then, you have a really bad
experience.

Thus we have decided to follow the save way which indeed
needs a bit more time, but we hope that people appreciate
consistency and stability over 2-3 minutes of time.

so long -
