We don't want to have separate /bin, /lib, /usr/bin and /usr/lib
directories. The former two are meant to be symlinks to the latter
two. The `split-usr` USE flag gets enabled with the profiles update in
portage-stable, so before doing the update, clear the flag in the
overlay.
This is not done for SDK images, since they seem to have split /usr on
purpose.
It is not used anywhere during the build process, thus drop
it. Dropping it makes it easier to port this ebuild to python3, since
there will be only one script to port to python3. The
`emerge-gitclone` script will need porting anyway, because it imports
portage code, which will become python3 after the update.
Most likely the package should be then renamed to
`coreos-base/emerge-gitclone`, but this can be done later.
Now that Docker 1.12 is gone, we can delete go 1.6 completely.
Note, we do not delete go 1.7, which is still needed by containerd 0.2.6
and docker 17.03.
Now that docker 1.12 is gone, we can delete `app-emulation/runc`
1.0.0_rc2, which had dependency on docker 1.12.
Note, we do not delete `app-emulation/docker-runc` 1.0.0_rc2, because
that one is needed by Docker 17.03.
Delete torcx config file needed only for Docker 1.12.
Note, let's keep the remaining file name as before,
`docker-1.12-no.json`, to be consistent with naming scheme of
the torcx repo itself of Flatcar.
One of the torcx profiles in Flatcar is for docker 1.12, which is
outdated since a long time. It takes ~27 MB of space in production
images almost for no reason.
We can and should delete docker 1.12.
After deletion:
```
$ df -h /usr
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/usr 985M 843M 91M 91% /usr
```
Using the change in https://github.com/kinvolk/init/pull/34
we can show the OEM on the motd, and by including "Pro" in the OEM
name we can also show whether it is a Pro image or not. Later this
may be revisited if the /usr/../os-release file is the place for it.
Update to 1.19.0, to keep up with recent releases of cri-tools.
Note that we should not simply update to 1.20.0, because its crictl
binary file is 30M, so bigger than the usual size.
On the other hand, crictl 1.19.0 is only 21M.
To optimize the binary size of crictl, make use of the existing
helpers provided by `coreos-go.eclass`.
Add "-X $(PROJECT)/pkg/version.Version=$(VERSION)" to GO_LDFLAGS,
as the original cri-tools Makefile does.
Note, we cannot run the native command like `emake crictl`, because
the cri-tools Makefile does not allow custom env variables like
BUILDTAGS or GO_LDFLAGS to be configured.
Add `arm64` to ACCEPTED_KEYWORDS.
Remove unnecessary files from installation, as well as the bash
completion eclass.
The bootstrapping script relies on /etc/docker existing, but this
directory doesn't exist on vanilla Flatcar. Add the missing call to
mkdir -p /etc/docker before the directory gets used.
Also, update the upstream files to their latest version.
