I think the subsequent posts have hopefully clarified the matter for Kent, however I had to make a comment about this:
This is telling me that my drive is full in the typical linux world. Course, this is all just RAM, etc. Remember, I used the OZ 64-0 image (no on-board storage). Could this be the problem?
No, this is not RAM, it's flashROM (hence the posts above saying that it might have become full). That's the point of the 64-0 image - there is no RAM disk (well other than the tmpfs... ;-).
maybe leave a bit of storage on-board--IS THIS WORTHWHILE?
IMO, no it isn't worthwhile.
I propose:
1. OZ 3.5.1 with a non-64-0 image (maybe leave a bit of storage on-board--IS THIS WORTHWHILE?)
2. Work solely towards getting the feeds working and then update all my OZ packages with the Upgrades feed.
3. Now install oz-compat.
4. Install opie-sh from the Opie feed to fix oz-compat
5. ...
What would step 5 be to get a fully functioning system (and before installing any other apps)?
Does this order even make any sense?
Yes, this would seem to be a good plan.
As zenyatta says, check that your SD is correctly mounted, but also remember that the symlinks and any configuration files which are written by the apps will take up space on the flashROM.
