Anything I can do to move this along?

Hey @lmb thank you for the pull request and the ping!

I couldn't get the 4.16 ACI to work, the VM hangs. I tested with:

$ ./builder
...
$ sudo rkt run --debug --insecure-options=image --stage1-path=aci-files/stage1-kvm-1.29.0-linux-4.16.aci docker://alpine --exec=/bin/sh -- -c 'uname -r'

Does this work for you? I'm guessing it's due to some of the VIRTIO options not set for 4.16.

Trying again with:

$ rm aci-files/stage1-kvm-1.29.0-linux-4.16.aci
$ rm -rf build/*
$ cp config/linux-4.14.config config/linux-4.16.config
$ ./builder
### do necessary config (mostly pick defaults)
### copy used config back
$ cp build/4.16/kernel/source/.config config/linux-4.16.config

... the test from above works for me.

Once the pull request is merged (and successfully build), all projects which use stage1-builder images have to be updated, since images are served from the CircleCI artifact store for the last successful build of master. We haven't got around to fix this yet (#27). That's why we are slow with merging things here...

@lmb if you want, you could also update rkt to v1.30.0

[lmb]

Done. I haven't had the time to run this through tests yet.

I was going to suggest keeping the old versions, but with bumping rkt version that point is moot.

https://github.com/kinvolk/stage1-builder/blob/master/builder#L51 also needs an update to 1.30.0

I was going to suggest keeping the old versions, but with bumping rkt version that point is moot.

I'll see to get to work on #27 soon. It's a pain as is.

Done.
