Title:
hook into system-image updates to precompile policy prior to reboot
To manage notifications about this
It’s good to have a more precise estimate of (i) recompilation time.
If/when we also get measurements for (ii) how long a restart usually
takes, and (iii) how long flashing usually takes, I’ll update the
specified progress bar allocation.

Note that the "15 minutes or more" is no longer the case and has not
been for a long time. AppArmor policy compilation for 150 profiles or so
should be in the 2-3 minute range (obviously, we still need feedback for
the user).

In the absence of any data, other than the fifteen minutes or more and
even up to 30 minutes statements, I've specified that recompiling
AppArmor profiles should take up the first 45% of the progress bar. If
we can be smarter about that, then great:
- An improvement would be to match the average

I'm sorry this was overlooked for so long.
A. Is it practical to use the device while precompilation is happening
in the background?
It Depends. We have some options in how aggressively we use system
resources, but probably even compiling one-at-a-time with a nice value
will definitely feel

We figured out a way to be able to do it before reboot, and this is
something that is needed for systemd and helps usability of traditional
apt systems in addition to system-image systems.
The idea is there are no extra steps for the user to go through, but yes
the idea is there would be a
I'm feeling the best we could do is actually doing it on first boot
after OTA, but make sure that we show a different splash screen while
this is happening.

This happens during the 'Google' logo on boot after flash and I'm told
there is no way to provide progress during this point. For traditional
apt based systems we will be employing a similar technique as outlined
in this bug-- during postinst we compile policy as needed so the user is
free to use
I'm not actually sure how you can compile them before reboot (so before
the update was applied), but if you say that's possible, I'm sure we can
think of something. We should probably stop the session straight away
and display a progress spinner akin to the one in recovery. I just want
to try and
Not really-- it was determined at the sprint that the recovery doesn't
have enough available to do this properly.
