I might do it another time - is that I'm more familiar (for when things
go wrong, and only because I have more experience) with usual partition
and not LVM and serve my purpose. As said, I might use LVM another time
:-)

I was asking "how to enter the passphrase only once" only to understand
why I'm entering it twice and not three times :-)

When I read it and also the initrd scripts I didn't understand why I
need to type it twice only when I was expecting three times... if I need
to read again some specific section let me know. I'll have another look
just in case.

Thanks for the other information! It might be handy at some point! :-)
