Installing Leap 15.1 Beta.

There were 5 LUKS partitions (sda5, sda8, sdb5, sdb8, sdc3).  I would only be
using sdb5 and sdb8 for this install.

I wrote down the UUID of those two partitions (well, the first part of the
UUID).

During install, the passphrase was requested.  The only choices that I could
see were to provide the passphrase or click "Cancel".

I clicked "Cancel" on the first two, as they did not match the UUIDs that I had
written.  I entered the passphrase for the next two.  And I clicked "Cancel"
for the last.

The installer then repeated the passphrase request for the three that I had
cancelled.  I again cancelled each of those.  Then it repeated again.

I gave up, and entered the passphrase.

There should be a way of telling it not to persist with requiring the
passphrase for partitions that you know will not be used in this install.

Will attach Yast logs.
