sysinstall problems upgrading from stable to daily latest

[Will Senn <will.senn%gmail.com@localhost>]

    As I was doing sysinstall
      against https, nycdn... NetBSD-daily, I experienced an issue that
      I don't know how to process:
      
      When I picked the destination, I chose wd1, the disk where I
      installed the system (I didn't read carefully or I might have
      chosen "current system"). The installer then did an fsck on rdk1
      and failed. I reran it and it succeeded, so I went on with the
      upgrade. At the end it complained about umount failing on / and I
      gather that's because I am currently running the system. After
      rebooting, things seem to work properly.
      
      I asked on irc and it turns out that rdk1 is a raw version of
      something called a wedge that corresponds to a partition? Anyway,
      mount shows dk1 as being /.
      
      All in all, I wonder if choosing "current system" is the answer to
      both problems - maybe it won't fsck rdk1 and won't try to umount
      /. Is this correct or do I have a real problem with my rdk1?
      
      Thanks,
      
      Will
