Comment(by Quozl):

 Replying to [comment:7 rsmith]:
 > My personal feeling is that any errors should not prevent the laptop
 from booting.  Is there specific reasoning for a corrupted bootfw.zip
 stopping the boot?

 Reviewing the code, I don't see any specific reasoning.  I don't remember
 any reasoning; I wasn't as involved back then.

 ----

 ''firmware-up-to-date?'' detects incorrect size of proposed image and
 calls ''.security-failure''.

 ''((fw-version))'' detects invalid version number of either the current
 firmware or the proposed image, and calls ''.security-failure''.

 ''.security-failure'' shows sad face (''show-sad''), and calls ''security-
 failure'', which delays 30 seconds and calls ''power-off''.

 On the other hand, once a firmware update is committed to, if not enough
 power present ''do-firmware-update'' merely skips the update.
