I use the following drop-in, but still error: "No such file or directory"
```
[Unit]
After=systemd-tmpfiles-setup-dev.service systemd-udevd.serviceAfter=sysroot.mount sysboot.mount
ConditionDirectoryNotEmpty=|/sysroot/usr/lib/repart.d
[Service]
ExecStartPre=/lib/systemd/repart-pre
ExecStartPre=/lib/systemd/repart-pre
```
In repart-pre, I checked /dev/gpt-part-boot and /dev/gpt-part-root actually exist.

I've had a bit similar issues. I think systemd-repart or generator services
which run after it provide /dev/gpt-part*. Thus systemd-repart can't use
these yet. I think you need adjust systemd-repart dependencies to wait for
the device nodes from udev.
