Hi,

I have working Arch LUKS on LVM & Void LVM on LUKS setups. I am now
trying to install Alpine LVM on LUKS on a partition on the same
laptop. From Void it looks like this:

/dev/nvme0n1p10 is for Alpine root & /dev/nvme0n1p11 is the
unencrypted /boot. /dev/nvme0n1p1 is the /boot/efi.

/etc/crypttab has:

But I don't get the decryption prompt while booting up, and instead
land into the initramfs emergency shell with /dev/mapper/alpine-root
mount failure error message.

What could be the issue here? Any help is greatly appreciated.
