Excellent.

"Any sufficiently advanced technol...." :]. The source is your guide,
but essentially itjust calls MoveFileEx with the correct flags on NT,
and on 9x creates a .ini file to tell windows to do the copies at boot
time.

Yes, there is more to do here - a list of what programs are in use and
the ability to wait for them to be closed would also be useful :}.
Patches gratefully accepted, meanwhile we are making progress.

Before? You got left with the old binary (couldn't be deleted) and no
package, or sometimes the new package files with one old file. Rather
bad behaviour IMO.

Very very wrong :}. It just failed. The resilience you saw is a credit
to Cygwin and the packages - it could have been much worse :}.
