Care to share an URL? 

atleo6:~#grep depenguinator /usr/ports/INDEX

However. If I understand you correctly, I need to boot this 
diskimage and then do a 'regular' install? Anything I could
also do, using a CDROM or a boot-floppy? Or is there some
other benefit?

The purpose of my live-upgrade mission is not to get rid of CD-ROM
or floppy requirements, but to minimize downtime.

Hmmm, I just have another thought... Possibly there is a way
to provide make installkernel/installworld with a different
destination directory?


make installkernel -DDESTDIR=/mnt
make installworld -DDESTDIR=/mnt

Would this be another possibility?

Best regards,
 Daniel Lang
