Previously we broke the cycle caused by sys-apps/util-linux only,
while disabling cryptsetup USE flag in systemd to avoid another
cycle. That worked before, because the follow-up merge of the rest of
packages built sys-fs/cryptsetup before sys-apps/systemd. After an
update, the new portage is ordering the builds in different way and
sys-apps/systemd ended up being built before sys-fs/cryptsetup and
that failed during the configure phase because of unmet dependencies.
Better build all the packages taking part in the loop (not counting
the virtual packages), so we become less reliant on the package build
ordering. It is going to take slightly more time as we build a couple
of packages more.
Instead of rebuilding just one package and maybe rebuilding others as
a fallout, force rebuilding all the mentioned packages. This makes the
build process a bit more robust against package build ordering
changes.
May be useful when breaking multiple dep loops that have some common
packages, so we build them all once.
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outdated since a long time.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
```
