This is nonsense. Just fix mount_mfs to not use entropy. newfs needs
entropy for NFS exports. MFS filesystems cannot be exported via NFS,
and a plain old random number generator will suffice just fine. It's
a simple fix to the newfs code (which mount_mfs incorporates to
initialize the MFS partition). We are talking a few lines of code here,
at best.
