After the Software Updater run of 7/9/2015, a new 3.13.0-57 kernel
(signed and unsigned) was added, and something added the "Boot0000,
ubuntu, shim" bootloader entry again, at the first position (where it
originally was). I did nothing explicit to add this shim entry, and the
machine is running with secure boot disabled. Attached is the
efibootmgr output and the diff of fwts outputs. My Ubuntu boot default
was restored, but something seems wrong with the update process changing
nvram.
