What I was referring to here was to just copy the cygwin local package 
directory that contains setup.exe and the http% mirror directories, not 
the directory that contains installed cygwin. When I moved the local 
package directory to a new machine and ran setup.exe with install from 
local directory, there sometimes were problems.

If there was only one http% directory

/http%3a%2f%2fwww.gtlib.gatech.edu%2fpub%2fcygwin%2f
/setup.exe
/setup.log

(meaning all of the cygwin install on the machine where I took the 
setup.exe dir from had been done from the same mirror)

then running setup.exe worked fine and I got a functional cygwin.

If found that if there were several mirror directories,

/http%3a%2f%2fcygutils.fruitbat.org%2fITP%2fmingw-gcc%2f
/http%3a%2f%2fmirror.cs.vt.edu%2fpub%2fcygwin%2fcygwin%2f
/http%3a%2f%2fwww.gtlib.gatech.edu%2fpub%2fcygwin%2f
/setup.exe
/setup.log

then running setup.exe would install only the packages in the last 
mirror used and there would be a number of things missing from the 
install (like the cygwin.dll). I did this before I knew that I could 
just move the entire installed cygwin directory to a different machine.


Regarding this set of instructions,
http://cygwin.com/ml/cygwin/2013-06/msg00657.html

they seem to be a bit more involved than is necessary. My cygwin install 
directory is less than 1GB, so what is the need to use tar? I believe 
that when I last re-installed my current OS, I just copied my cygwin 
folder to a backup drive and then copied it back to C: after my 
re-install. Is there some reason why that is a bad idea?
