Merge lp://staging/~mvo/snappy/lp1480248-test-reenable into lp://staging/~snappy-dev/snappy/snappy-moved-to-github

This needs the bbb oem v1.12 to be released: https://code.launchpad.net/~mvo/snappy-hub/lp1480248-norootwait/+merge/269032

Also, in order to test it we need to fix the arm build in the tests: https://code.launchpad.net/~elopio/snappy/goarm_tests/+merge/269391

The test is failing with:

/home/elopio/workspace/go/src/launchpad.net/snappy/_integration-tests/tests/failover_zero_size_file_test.go:248:

For some reason, it's looking for the backed up file in the a boot. /me digs more.

The tests needs this change to pass:

There's something weird in there, because the comments of the afterUpdate parameter in the helper function don't seem accurate. I'm making a note to ask Federico about this.

Thanks a lot! This is addressed now.

With this changes I get an error on kvm: [1]

It seems that the function that determines the kernel filename pattern is wrong for uboot based systems, this patch [2] makes it work for me on both grub and uboot, could you please confirm?

Thanks!

The test should be reenabled now. However because of the latest changes the diff no longer applies, this one works [1]

Thanks,

Thanks Federico! And sorry for the slow reply. This should be ready again.

Test passes. Thank you!
