Performing a fresh Disco (daily build from 2019-03-31) server install with / mounted from LVM over dm-crypt (over mdadm), the boot fails just after asking the encrypted partition passphrase with the following error:
/scripts/local-top/cryptroot: line 1: fold: not found
Building a custom busybox package with "fold" binary enabled for busybox-initramfs and busybox-static configs fixes the issue.

It might be enough to add "fold" to the initramfs variant only.
Normally one should have plymouth installed, and fold code path shouldn't be used.
Do you not have plymouth installed, and/or does it not work in you environment?
