Re: Some help with [re-]installation please


Since none of this is really specific to Cygwin/X, I've redirected this
thread to the main cygwin list.

I'll take a stab at a few of these, but there are parts I am not
sure of either.

Yep.  My 160Gb main drive in a brand new Dell box died in less than a
month.  I had just got the box up and configured, but I had no backups yet
:(.  So, I sympathsize.

Yes.  Choose "Install from Local Directory" instead of "Install from
Internet", and point setup there.  Keep in mind, however, you would have
missed out on all the new and exciting updates :).

I think it uses the "Local Package Directory" that it prompted you for as
a cache.  So, I think the answer is yes.

I found it confusing at first too :).

No, it is more of a view of what is to come ie. the packages that you or
it have selected to upgrade/install.  Does that help?

Did you try it?  Clicking on Keep transitions it to Uninstall, Reinstall,
Source, etc.
