I have a hack to get around this:
koen@dominion:/OE/tentacle/sources/meta-openembedded/meta-oe/recipes-core/systemd$
git diff .
diff --git a/meta-oe/recipes-core/systemd/systemd_git.bb
b/meta-oe/recipes-core/systemd/systemd_git.bb

But I wonder if we should fix it differently. We already have this one:
koen@dominion:/OE/tentacle/sources/meta-openembedded/meta-oe/recipes-core/systemd$
cat ./systemd-compat-units/machineid.service
[Unit]
Description=Machine ID first boot configure
DefaultDependencies=no
ConditionPathExists=|!/etc/machine-id
After=remount-rootfs.service
Before=sysinit.target
[Service]
ExecStart=/bin/systemd-machine-id-setup
RemainAfterExit=No
Type=oneshot
StandardOutput=syslog
[Install]
WantedBy=basic.target
WantedBy=sysinit.target
Which apparently is too late.

Koen
