Yes, entering the LUKS volume passphrase twice is normal, though I would
love to hear about ways to improve it.  As I understand it, both GRUB
and Linux have to unlock the LUKS volume, and they do not by default
coordinate in any way - that is why you have to enter it two times.  I
don't know how to arrange for a password to be entered only once, but I
imagine that it may be possible, with varying degrees of security
depending on the chosen solution.
