[systemd-devel] new job systemd-cryptsetup at arkluks.service/stop - Why?

[Dave T]

prevents keyfile being placed on removable storage ·
Issue #3816 · systemd/systemd
https://github.com/systemd/systemd/issues/3816

I used your explanation as it was better and more clear than anything I
could have written.
