With genkernel, I don't know; I never used it. On the other hand,
dracut is designed to work with systemd; if you use the systemd USE
flag and the systemd module, it even uses systemd *inside* the
initramfs.

The problem obviously is not in systemd, but in the integration of
genkernel+systemd. I repeat, I never used genkernel, so I don't know
what you can do.

That being said, "get a complete history of systemd actions in the
order that they are done" will not tell you much: systemd uses heavy
parallelization, so in some runs the order in which actions are
performed will be different from others.

The problem is that if systemd is installed into /usr/lib (which is
Gentoo's case), then /usr should be mounted before systemd starts.
That's responsibility of the initramfs, not of systemd, and the
solution lies in the initramfs, not in systemd.

My only possible recommendation would be for you to try dracut.

Regards.
