Note that dpkg-buildpackage will try to retain symlinks that exist in the debian/ directory and you can easily end up with a package containing a symlink to /home/thomas/foo which will break on any other system, even if the user is called Thomas! You can use symlinks in the upstream source, maybe in SVN etc., but when you prepare a directory to build the Debian package, you must take care that files in debian/ are actual files and that symlinks in debian/ are correctly installed so as to symlink to the final location under /usr/ etc. Using environment variables could let you down (the environment is subject to user control) - it could be more reliable to test for the existence of an executable file /usr/bin/package1 or /usr/bin/package2 etc. Otherwise, your maintainer scripts could fail under a chroot or similar. > Third, as I have debian/package1.cron.d and debian/package2.cron.d > being the same, I've renamed them debian/package1.package1.cron.d and > debian/package2.package1.cron.d and used dh_installcron > --name=package1 to be sure that those 2 config files are same.

The package1 prefix is probably being stripped - check how the cron file is being prepared upstream. You may be better off using separate files that call their own packages using hardcoded strings. The other alternative is to have the cron file detect which package is installed (maybe by testing if /usr/bin/foo1 is an executable file etc.) so that there is only one cron file for package1 or package2 but it knows how to handle whichever is installed. Can the user choose to install package1 and package2 on the same system or have you got a Conflict: setup? -- Neil Williams ============= http://www.data-freedom.org/ http://www.nosoftwarepatents.com/ http://www.linux.codehelp.co.uk/
