Automating Package Updates

[Alan Dobkin]

Has anyone developed a mechanism to notify and automatically 
update Cygwin packages on deployed systems?  I've searched 
the list and haven't seen anything like this yet, so I'm 
working on a perl script do it, which I will share if 
there is interest.  The idea is similar to RedHat's RHN/
up2date program for Linux.  But if something like this 
already exists for Cygwin, then I won't reinvent the wheel.

The script I'm working on requires Cygwin to already be 
installed, so it's not intended as a replacement for the 
setup program, and it would probably no longer be needed 
once there is a command-line setup.  It also requires perl 
to run, along with bzip and tar for package installation, 
ssmtp for e-mail notification, and cron for automation.  
It compares setup's installed.db file with the latest 
setup.ini to determine what has changed.  If it updates 
any packages, it revises the entries in installed.db and 
the package contents files in /etc/setup to keep setup 
happy for future manual updates with the GUI.
