Hi I was reading about how unlock encrypted root partition from remote
(unattended). I'd like asking what is compatible way for this in centos
and commonly used by administrators?

I think most simple is install dropbear in initramfs for allow remote SSH
and manual enter passphrase. I find many HOWTO for that on debian/ubuntu,
but nothing for centos.

Is there any help, recommend or HOWTO available for centos?
