I was wondering if there was a way to save and duplicate my cygwin

The following has worked for me over more than 6 computers since 99:

Shut down all cygwin apps, including installed services. Archive the entire
cygwin directory with WinRAR (shareware, and so much better than any xZip,
will preserve symlinks).
cd to the cygwin dir and save all ntfs file permissions using Pedelstal
Software's NTSEC suite (shareware and still available at
http://www.winsite.com/bin/Info?500000034210), more specifically using
saveacl -r -usepriv * cygwin_permissions.txt
Use your text editor of preference and globally search and replace any user
names that have changed between the old and the new computer in
Unpack the cygwin archive to your new location on the new computer.
That seems like a lot of work to go to when you could just use tar to create
the archive. It will create files with the proper permissions.
But what if the user name is changed on the new machine? What about the
SIDs in /etc/passwd and /etc/group? Do mean that when passwd and group
are regenerated and if the user names stays the same everything will
have the right permissions after untarring?
But then one might have things like postgresql and mysql file structures
(like I do) that tar can't access (even if run as SYSTEM). The saveacl
program with the -usepriv switch gets those as well. What about ssh
