Well, that's your choice. I can't say that it helps us develop setup
though.

Quite possibly. Or at least, *I'm* not doing the *same thing* you have
been.

I'm pretty sure we have addressed all but the download incomplete issue.

Use a mirroring tool.

I don't understand how this is different to update. I routinely
add/remove/update packages from my install with setup.exe.

1) Is a virtual thing, it doesn't really make sense to me, never has,
but I put it in in an attempt to satisfy an apparent user demand. It's a
special case of 2) and 3).
2) Is a special case of 3)
3) Is all that setup knows to do. It automatially selects updates to any
installed packages, automatically chooses to install anything in 'base'
or 'misc'.

I repeat ... for the nth time ... I can install and reinstall setup*src*
as many times as I want, with a new cache, or a full cache, with no
errors. I haven't tried the exact click recipe the earlier poster
provided yet - and you can be sure that IF I can reproduce the bug it
will get addressed. HOWEVER, may I point out that repeating your
frustration with that particular 'feature' is rapidly exhausting MY
patience, and unless you intend to fix the bug yourself, you might like
to focus on providing NEW information.

Default means to follow the default behaviour appropriate for that
package, based on any heuristics present in cygwin. It may mean
installing it, or ignoring it. Currently, due to policy, it does not
ever mean reinstall or uninstall. In the future it may mean popping up a
conflict resolution window to resolve conflicting packages.

Default - Follow the default behaviour for every pacakge.
Install - Toggle the action for every package contained in the current
container to install the current trust level. If the current container
is a leaf node, then just that package.
Uninstall - Toggle the action for every installed package contained in
the current container to uninstall. If the current container is a leaf
node, then just that package.
Reinstall - Toggle the action for every installed package contained in
the current container to Reinstall. If the current container is a leaf
node, then just that package.
