Preseeded installation doesn't reboot unless ubiquity/poweroff is also set

[Daniel Manrique]

Binary package hint: ubiquity

Ubuntu release: natty daily from 20110301
Ubiquity version: 2.5.21, revno 392

It used to be that we could get preseeded, automated installations to reboot when finished by setting:

ubiquity ubiquity/reboot boolean true

However, this stopped working recently. I found out that we now need to set two values in order for the system to reboot when finished:

ubiquity ubiquity/reboot boolean true
ubiquity ubiquity/poweroff boolean true

I tracked down the change to Ubiquity 2.5.13 where code was added to ubiquity/frontend/gtk_ui.py and ubiquity/frontend/kde_ui.py, to fix bug #690726. Starting in that version, for the system to *either* reboot or shutdown (the latter via ubiquity/poweroff), *both* of these options have to be set to true.

The code expresses this but it seems to me that it's incorrect, and one should be able to get a reboot or shutdown by setting only the actual, desired value. What's more, if they are both set, ubiquity/reboot takes precedence because it comes first in the code, meaning that the section of code that issues a shutdown will never get called.

The problem line (610 on gtk_ui.py, 483 on kde_ui.py) says:

elif not self.get_reboot_seen() or not self.get_shutdown_seen():

should be:

elif not self.get_reboot_seen() and not self.get_shutdown_seen():

or (I think it's clearer):

elif not (self.get_reboot_seen() or self.get_shutdown_seen()):

The attached patch implements the proposed changes.
