It has been discussed many times that supporting separate /usr without an
initrd is a pointless waste of time. There's so much effort that affects
hundreds of libraries or other packages with only extremely tangential
relation to booting, and only in very specific configurations, that it's
simply not worth it. Just use an initrd.

But, as you say, the problem _does_ happen for you with initrd. This means:
1. moving the libraries to /lib wouldn't help,
2. is not related to split /usr (as you mention whole-disk encryption),
3. is in no way specific to Devuan

Thus, as you use pieces unmodified from Debian, please report the bug there.
A fix there would help far more users than just the Devuan's subtree of
Debian derivatives.
