Weird.  Order shouldn't matter.  The code in the var script is really
simple.  It creates the md file system if you have varmfs="YES" or if
"/bin/mkdir -p /var/.diskless" fails.  Hmm, I just noticed that ru never
MFC'd the fix to add -p to that command.  Do you have a /var/.diskless
on /dev/ad0s3d?  If so, that's probably the problem.
