[p2-dev] Difference between "revert" and "uninstall"?

[David M Williams <david_williams@xxxxxxxxxx>]

(Sorry to ask a "user question"
here :) 

I'm working on some "feature patches"
for 4.3.2, and noticed that I can use the history view in the about box
to "revert" to previous level (effectively uninstalling the patches).
But, if I select the patch features and say to "uninstall" it
fails. Error message in Bug 428087.


As long as users have a means to "undo" what
they did, I'm not too concerned about this specific case ... but, wondering
if its a sign that I'm doing "something wrong"? Or is there a
purpose to the difference?
