I updated the kernel with the latest source (the world has been installed from the source as of 4cc93e2d), but I'm afraid it doesn't fix the issue. Here's how you compile GNU screen from git master, by the way: $ git clone git://git.sv.gnu.org/screen.git $ cd screen.git/src $ autoreconf ./configure gmake ./screen (and press ctrl+D or type `exit' followed by Enter key) An window still takes about 10-seconds before closing if it was running a shell. The shell process itself is terminated right after pressing ctrl+D, according to the output from ps command. Bisecting revealed that the first commit in GNU screen which takes longer to close a shell window on a recent DragonFly kernel is: http://git.savannah.gnu.org/cgit/screen.git/commit/?id=33b7c9ca I also noticed that issuing shutdown command from within screen triggers a kernel panic, if it proceeds within the 10-seconds delay. I don't use a special CFLAGS to build the kernel, and I use gcc4.1 (no CCVER specified).

() This 10-second-wait should be fixed with commit 847ff8c. While debugging I noticed screen calls close(2) on all descriptors except stdin/err/out every time it forks. Making it use DragonFly's closefrom(2) would be a great optimization that would reduce new window creation times, if anyone felt so inclined. Sam

How do I downgrade pkgsrc to match pkgin? The version of pkgsrc you have installed is shown in whatever tag it's against - /usr/pkgsrc/CVS/Tag contains the tag. It should be pkgsrc-2010Q1 to make sure that when you build manually, you're building the same versions as what pkgin is downloading from avalon. If it's not, you can manually make it match and then update with setenv CVSROOT anon...@anoncvs.netbsd.org:/cvsroot setenv CVS_RSH ssh cd /usr cvs -q update -dP You can also delete /usr/pkgsrc and restore it with exactly the version you want with: setenv CVSROOT anon...@anoncvs.netbsd.org:/cvsroot setenv CVS_RSH ssh cd /usr cvs -q checkout -rpkgsrc-2010Q1 -P pkgsrc (notice only the last line is different.) If there's no tag, you're building from the bleeding edge of pkgsrc, which will get you the newest versions but also the newest issues, and is very likely the cause of these version mismatches. I would advise: - Making sure you have pkgsrc-2010Q1 as your /usr/pkgsrc/ - Make sure that pkgin is pointing to the right repository of files on avalon. 2.7 should show in the path, since you are running 2.7. You should be able to build everything at that point. (Look at pkg_rolling-replace if you want something to run through every option for you.) I am working on new pkgsrc-2010Q2 binaries, but it will be at least a few days before those are available, and I'll send out an announcement when they are. When they are available, do as before: make sure your local /usr/pkgsrc is updated to that release, and I'll mention when the /stable/ link for pkgin is updated to point at packages with that newer release. You mentioned before that you are downloading 2.6 packages on a 2.7 system. That can work right now, but it's better to match exactly. Look at the path set for pkgin.
