Of course, they can just call `package-activate-all`.

This is orthogonal to `package-quickstart`.

Yes, I still have to sleep on it, I think, but I'm beginning to like the idea.

Yes, I think we should.  But for that we need to make sure the
quickstart file is properly recreated every time it's needed.

There might also be situations where that can't be done, tho: e.g. if
`package-directory-list` includes a directory maintained by the
sysadmin, then we won't be told when packages get
installed/removed/upgraded in that directory.  To handle such a case
we'd have to either disable quickstart altogether or add some kind of
"freshness" check at startup before using the quickstart file.
