Yes. Is there a way to accommodate that? Maybe a postinstall script
checking for existing user cron files and renaming them if required?
The privileged user name shouldn't matter much after configuration.

I just scanned it quickly, but the change looks good.
For all of this, apart from the Cygwin-internal stuff, I'm in the same

this change will have, and we might all be missing something crucial
during the transition.

Yes. It's still supposed to be used if somebody needs passwd entries
for some reason. For the details, see the preliminary documentation
Note also the discussion with Christian starting at
