Re: [PATCH 1/3] Compare package versions, not setup.ini timestamps

I'm not against this idea but I'd like to see what others think about

I know that cygwinports and other sites use setup.exe for their own
purposes but setup.exe was never really intended (Red Hat itself not
withstanding) to be used as anything other than a mechanism for
installing the cygwin distribution.  So, while, again, I am not against
this idea, I'd like to see what others think about this.  It doesn't
seem like we'd lose any functionality if we adopted this change but I
may be missing something.
