This is a downside of having only a general and not also a "technical"
mailing list to discuss and diagnose "technical" issues and approaches.
The suggestion was intended as a tip to ensure *complete* locally
rebuilt package contents are installed, by folks who are already having
issues with their installation, rebuilding Cygwin and packages, and
replacing the Cygwin dll etc. and packages to diagnose those issues. So
hopefully they are also aware of preremove and postinstall scripts, in
packages where they are provided, and the /etc/setup/PKG.lst.gz
manifests for files to be removed before installation, and provided
after installation. For the latter I would expect technical folks to
make use of them but leave them to Cygwin Setup programs for officially
released package upgrades.
[Also some of us do not have the appropriate technical background and
expertise to get a Cygwin overlay mirror working reliably from the
available instructions (if it was easy enough, someone would have
provided a local-overlay-mirror package to do it years ago), nor systems
fast enough to run Cygwin Setup for every package install.
Due to Windows "improvements", my system upgraded a few years ago is
just as "fast" as the 10 year old system it replaced. ;^>
Cygwin Setup upgrades can take as long as Windows Update installing the
latest patches.
Some of my approaches, suggestions, and participation here are coloured
by those limitations (also by expensive, slow, uncompetitive networks).]
