I really don’t know what to suggest here. As you mentioned, this used to work. If you are only using LUKS for swap, maybe you could just remove it from crypttab and run the appropriate commands manually in rc.local or a custom systemd unit.

Timing problem? Status in zfs-linux package in Ubuntu: New Bug description: Hi, first of all: I don't know if it is a bug in cryptsetup-initramfs or zfs-initramfs or another one. The problem is that since my upgrade from bionic to cosmic the cryptsetup tries too early to setup my cryptswap device which is on a zvol. cryptsetup: Waiting for encrypted source device /dev/zvol/rpool/swap... ALERT! encrypted source device /dev/zvol/rpool/swap does not exist, can't unlock cryptswap1. ... After timeout I find myself in a initramfs-shell (initramfs). When I do zpool list there is no zpool importet. After zpool import -N rpool ^D the cryptsetup succeeds.
