Comment 4 for bug 1468410

@Caio,
Sorry, I missed some comments.

For #3, I can not access capomastro staging server, guessing you need to open my permission, if convenient please also open yc and vicamo's permission for testing.

For #1, 1), Yes, so far, I think --autobuild is enough instead of using local tarballs. But we still need the parameters follows --autobuild.
  ex. --autobuild --channel ubuntu-touch/rc/meizu.en
  ex. --autobuild --channel ubuntu-touch/rc-proposed/meizu.en
And I also plan to have one more parameter to get different build version on system-image.u.c
  ex. --autobuild --channel ubuntu-touch/rc-proposed/meizu.en -r 32

For #1, 2), And I think this script can be used by Krillin as well.
But because mkflashable.sh used make_ext4fs which built from tree, so still need to confirm if Krillin have same in-tree tool.

@ John McAleely, Maybe you have some comment for this question if you are interested in making mkflashable.sh support Krillin as well.

For #2) mkflashable.sh assumed some fixed path exist, so it need some prepared before executing when trying to execute it without checkout whole Tangxi project:
1. MAKE_EXT4FS=ubuntu/tools/make_ext4fs
2. origin/m75_ubuntu-daily branch of manifests module exist in ".repo/manifests"

Hope these can help :)
