You are, it's the hook that copies the cryptsetup binaries to the
initramfs…  And /scripts/local-top/cryptroot is run whenever you have
encrypted devices that need to be unlocked at initramfs stage (whether
or not some of these devices are using ‘keyscript=decrypt_opensct’).

No need, it's enough to check whether ‘/usr/bin/setleds’ exists, like
we're doing for ‘/usr/bin/gpg’ and some other binaries.

That being said I don't think restoring the numlock state is the job of
cryptsetup's initramfs hook & boot scripts, just like it's not its job
to install the right keyboard layout.

I'm therefore reassigning this to ‘initramfs-tools-core’, which is the
package shipping the keymap hook.

An option would be to store the state when generating the initramfs
image, but that doesn't seem to be exactly what you want.  With full
disk encryption I don't know where else to store the state at shutdown
stage.
