  I didn't know that mbrlabel could do this. I thought that it just
installed partition tables.  (Disk actually has 4 installs of RedHat,
thus the weird partitions. 
  Nice to have mbrlabel.  It is new (to me).

Is it possible that my kernel config is missing something to permit
additional partitions in the list? no, it won't even let me mount wd1a.

Note that "disklabel wd1" produces a different answer. Maybe it's version
got installed first. I'd hate to have to reboot to deal with this?
