So, it seems some things depend on lz4.  But nothing mentions it directly.

But, here's the problem -- lvm2 depends on
/lib/x86_64-linux-gnu/libsystemd.so.0 and *that* depends on liblz4.

This is sad.

To allow /usr-less booting either lvm2 should not depend on libsystemd,
or liblz4 should be moved to /lib.
