I must be doing something obviously wrong.  I picked up a snapshot of a few days ago and tried to install it by replacing the binaries, then tried to upgrade with the 20040710 installer (I run 0.6.1 normally).
In both cases I get:
colinux: manager open: last error: The system cannot find the file specified.
Cooperative Linux Daemon, 0.6.2
Does anyone understand why this might be?
