I tested the exact same disk layout and encryption scheme on Debian and Kali Linux, both installed via UEFI with separate EFI and /boot partitions, plus two distinct encrypted LVM volumes for root (/) and /home. Each LVM volume is backed by a separate LUKS container, each using a different passphrase.

Debian behavior:
    At boot, Debian prompts for the root volume passphrase. Once entered, it proceeds to prompt for the /home volume passphrase. After entering both passphrases, the system boots normally with both volumes mounted.
Kali behavior:
    Kali only prompts for the root volume passphrase. After unlocking root, it continues booting without ever asking for the /home passphrase, leaving /home unmounted. The system either drops into emergency mode or boots without /home. Attempting to enable command-line mode or disabling Plymouth does not fix the issue; Kali never provides a second prompt for the additional encrypted volume.

Key Observations:

The partitioning/encryption scheme is identical on both Debian and Kali:
    EFI partition
    /boot partition
    Root (/) on one LVM-on-LUKS container
    /home on a different LVM-on-LUKS container
Each LVM-on-LUKS container uses a unique password.
Debian consistently prompts twice (once for each container).
Kali never shows the second password prompt, even with Plymouth disabled.
