it may be a good idea to try and remove this requirement from the instaler if possible
cygwin uses shared memory and different versions of the dll do not play nice might be an idea to look at the mingw tools instead

It uses some of the Cygwin binaries during the install.  It copies the Cygwin binaries into the TEMP directory, runs them from there, and then removes them by the end of the install. They are never installed on the system.  This is no different then Microsoft or other installers that use a VB runtime
or other needed installer executable during the install--it is just the opensource equivalent.  Note that Cooperative Linux still has no dependency on Cygwin and that the system being installed to may or may not have Cygwin before and after the install.

It is using the Cygwin tar.exe to unpack the root filesystem and swap device device files in sparse form.  This is the best way that I currently know of to deliver these in sparse form. Check the documentation I posted earlier for the space savings this gives to the users.

I am also using the Cygwin perl.exe to produce configuration files and command files with the appropriate settings that the user has selected during the install. This could be done in other ways--I am just most comfortable in perl (other people
may prefer python or something else).  I have added to the end of this message the perl script that I currently use for this.
