Currenly miniramfs has this in its Depends: line:

 Depends: busybox | busybox-static, ...

The busybox-static alternative is not needed, since busybox-static
package already Provides: busybox, so it will satisfy the first
alternative.

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

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

Thanks,
