I thought that permanent postinstall scripts run even when no packages are being installed, or only packages are being removed, so they they are effectively run every time setup is? >> Unfortunately, it's not very practical to change to doing that for the all >> packages which contain info files, so I am suggesting this approach. > > So just do it unconditionally; I was planning to change _update-info-dir > accordingly, but haven't found the time yet.

Tempting, but I don't believe that is a good solution, since it adds the time it takes to rebuild the info directory to every setup run. > $ time /etc/postinstall/update-info-dir.sh.done > > real 0m18.169s > user 0m3.261s > sys 0m5.703s I also don't think it sets a good example. Any other packages which require update scripts to run (which may take even longer) when packages are installed/removed, should not be doing that every time setup is run, if avoidable. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
