If this is a fresh installation, you'll usually want to reboot and check that 
everything
went smoothly anyway.  If you've already lost the passphrase at the end of the 
install
process then at that point you'd need to re-install anyway for a usable system, 
so
rebooting to check that you have the correct passphrase is not really an extra 
burden.

Yes.

Full disk encryption - Verifying/changing passphrase

[patrick keshishian]

Hello,

For the first time I decided to set up full disk encryption on a new
drive. Process went smoothly!

Anyway, here are two possibly silly questions:
1. How can one verify they remember the passphrase before
rebooting/shutting down?
2. What is the process (steps) to change/update the passphrase?

Is the process simply running "bioctl -P sdX"? And entering old and
then new passphrases?
