The tests (and the specification) expect a Format to destroy all previously written data. The bhyve NVMe emulation implements this by trimming / deallocating all data from the backing-storage. The blockif_candelete() function indicated the file did not support deallocation (i.e. fpathconf(..., _PC_DEALLOC_PRESENT) returned FALSE) even though the kernel supported file hole punching. This occurs on builds with Capsicum enabled because blockif did not allow the fpathconf(2) right. Fix is to add CAP_FPATHCONF to the cap_rights_init(3) call.
