You would delighted to know that not everybody do like this. We prefer
let the employees decide when the time to update is right, due for
exemple factor like "having to leave the office soon", or "being at a
customers site without much network connectivity", etc, etc.
As i say, we mostly have a fleet of laptop, and of course, the situation
would be different if this was a set of workstation, but alas, this is
not the case.

as long as this is automated, this is a technical detail. People seeing
2 times the bios do not really matter. Granted, this is annoying to have
to enter your encryption password twice if you use luks, but I wonder if
kexec cannot help on that part.

and so ? If the upgrade is the reboot, this is to be expected.
AFAIK, the update is not applied until you reboot, and AFAIK, you can
still do stuff by yourself using yum. So if your point is "you cannot
use the update before the update is applied", I have yet to find what
you mean exactly.

Then this mean there is a problem in dependency. If I install kevin-
simulator-1.0 that requires libmichael1.1 while libmichael1.0 is
installed, either it need it and it will pull it, or it doesn't need and
it will not pull it. This also ask the whole question of having non
compatible library, etc, but I think we already answered that question
with the update policy and need to keep a proper compatible ABI.
> * security fixes also only take effect after the reboots.
unlike now, where they take effect based on random factors such as "was
firefox already running", or "did I logged out after the update", or
"did I reboot on the new kernel" ?
At least, the new system bring coherency, you know that everything is up
to date after the reboot. And again, if you like the previous way, you
can still opt-out of the system.
> It also violates the principle of least surprise.
In what way ? If the system clearly say "we are gonna need to reboot to
apply thoses updates", it is hard to say that you are surprised. And the
principe of least surprise would be violated if we didn't followed the
dominant paradigm, which is still windows afaik.
