It needs to detect, otherwise the upgrade process will have to set the
said environment variable. In case the customer wants to downgrade, the
environment variable has to be modified as well instead of simply
rebooting back from the original flash. It would be much easier for
everybody if there is one less thing to worry about.

I don't think it needs to detect.  I'm happy if there is an environment
variable that specifies to boot linux or boot bsd.  If it doesn't work,
can't find the partition or the file, then too bad.  But I do want to
be able to specify the file to boot, ie., I want to be able to boot an
arbitrary file on the compact flash, or at least an arbitrary file in a
specific directory.  Currently it only boots /bsd IIRC.

Cheers,
