Your domain user SID will remain the same, however, all of the local
machine's domain SIDs will be different as it is a different host on
the domain, so I would expect permissions problems for any/all machine
specific installations when doing a raw perms copy.

I usually do this via script.  Besides, after copying, unless you
first do a full update on your source every time you'd still need to
update to current for the latest fixes.

I would imagine all of the *files* are present in the cygwin root, but
I've never checked, and a simple file copy, even if the adjustments
are made to result in the correct permissions, will not get things
like registry entries.  (I don't know how many there are, but do know
I've seen some).
