Currently open-iscsi package has this in Recommends: line:

  Recommends: busybox | busybox-static

The second alternative is not needed, since busybox-static package already
has Provides: busybox, which will satisfy first alternative.

However, we're currently making changes in busybox-static (see #1147074),
which will make it incompatible with open-iscsi expectations.

Please drop busybox-static alternative from Recommends to allow us to
proceed.  This is a trivial change.

Thanks,
