Hi all,
I'd like to add another suggestion:

6. User starts R. R crashes with "Fatal error: unable to restore

'fortunes'".
I would find it very useful if the installer offered an option to copy
extension packages from the old version to the new version. Apart from
possibly preventing this type of crash, it would save the hassle of
reinstalling or copying the extension packages one regularly uses.
Often the old packages won't work in the new version, and you need to
call update.packages(checkBuilt=TRUE) to update them. That means that
to install R, you would need an active Internet connection (or at least
the ability to check for one). All of that is possible, but it's not
trivial to get it to work smoothly, and to handle errors when things go
wrong (e.g. packages that are no longer available).
I think it would be better to move all of those details out of the
installer, and into a user contributed package. Then the maintainer of
that package will handle the headaches, not me.
