Thanks, Paul
I successfully created custom buster iso. But my persistent-encyption
was not detected by the live system I created. I of course did include
cryptsetup in package list. I read some archived emails and they seem
to indicate that the boot append live setting persistent-encryption=luks
from stretch needs to be "luks1" in order to work on buster. Is that
the only change necessary for "persistent encrypted" to work?
