+    dbus-proxy: Make it work if XDG_RUNTIME_DIR not set
+    
+    The socket directory then ended up in $HOME which was read-only, so
+    we couldn't create the socket. We solve this by putting the sockets
+    in a subdirectory and always making this directory writable in the
+    proxy.

+Flatpak
+
+Flatpak is the new framework for desktop applications on Linux
+
+Distributing applications on Linux is a pain: different distributions in
+multiple versions, each with their own versions of libraries and packaging
+formats. Flatpak is here to change all that. It allows the same app to be
+installed on different Linux distributions, including different versions. And
+it has been designed from the ground up with security in mind, so that apps
+are isolated from each other and from the host system.
+
+Some of the examples from http://flatpak.org/#users are relying on polkit
+helpers, that expect a user in the 'wheel' group to have privileges for, but
+default polkit admin rule for slackware is just the root user.
+So, if you run a command like:
+```
+flatpak remote-add --from gnome https://sdk.gnome.org/gnome.flatpakrepo
+flatpak remote-add --from gnome-apps https://sdk.gnome.org/gnome-apps.flatpakrepo
+```
+as a limited user, you will get a polkit prompt for root's password. This is
+because the default location for establishing these repos is in
+`/var/lib/flatpak` and requires admin privileges.
+
+You can optionally add the flag `--user` to flatpak commands, and it will
+instead manage the repos in `~/.local/share/flatpak`.
+
+There are examples of flatpak runtimes and applications on their wiki:
+https://github.com/flatpak/flatpak/wiki/Examples
+
+The to have desktop launchers search by desktops like KDE and XFCE, it will
+require a logout, as /etc/profile.d/flatpak.sh will need to be sourced.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
