Guys, This is a curiosity really. I updated kdebase to create a trinity.desktop file in /etc/X11/sessions in the PKGBUILD package() function: # install desktop and update kdmrc and Xsession [[ -f trinity.desktop ]] && { mkdir -p ${pkgdir}/etc/X11/sessions cp trinity.desktop ${pkgdir}/etc/X11/sessions } <snip> Since I had already created trinity.desktop on my box (before it was part of the package), I get (correctly): Targets (1): trinity-kdebase-1221588-1 Total Download Size: 0.00 MB Total Installed Size: 86.71 MB Proceed with installation? [Y/n] checking package integrity... checking for file conflicts... trinity-kdebase: /etc/X11/sessions/trinity.desktop exists in filesystem IIRC this is exactly the way pacman is supposed to work because it has no knowledge of a prior trinity.desktop in the filesystem and won't overwrite it. The short answer is "dummy -- remove the file or use --force." I get that. The question is "Can I do something in the PKGBUILD to tell pacman - if the file is already there -> overwrite it?" The purpose for the question is make sure nobody else gets a conflict if they have followed a prior manual Trinity kdm install proceedure. -- David C. Rankin, J.D.,P.E.
