Merge lp://qastaging/~dpigott/lava-master-image-scripts/deployment-improvements into lp://qastaging/lava-master-image-scripts

Lots of changes, good stuff, two comments:

0) Bzr workflow is sucky verbose, meh

1) The fix for panda is wrong, the first boot will still experience all the issues that line prevents. After changing sysctl config reload it (I don't recall the command not but it's probably sysctl -p

2) Can we move the partition step to happen at first boot please? It should be easily doable now. I know it's a lot to ask for so this can go in (noting that 1) needs to be fixed).

1) Sort of - we always reboot before doing anything, so the fix gets loaded
2) Completely agree. It's doable and I shall do it. :)

I think I agree with Zygmunt that having a sysctl -p would be a bit cleaner although it's not really necessary. Doing the partitioning at first boot would be awesome but that can be in another branch :-)

WRT the streaming errors, it feels like we're stepping around a kernel bug really. Have we talked to any kernel people about it?

Anyway, add sysctl -p and merge please!

You can use:
imx53|origen)
SCHEME=3part;;
snowball|vexpress)
SCHEME=2part;;
beagle|panda)
PRE_ENV=Y
SCHEME=2part;;

to decrease duplication.

Spring: I tend to not like doing that, because at some point we may well want to add some more board specific stuff and then we end up having to split them anyway.
