322345fdb9865ef2477fba8e4bdde0e1183ef505Lennart Poettering* support sd_notify() style notification when reload begins (RELOADING=1), reload is finished (READY=1), and add ReloadSignal= then to use in combination
322345fdb9865ef2477fba8e4bdde0e1183ef505Lennart Poettering* support sd_notify() style notification when shutting down, to make auto-exit bus services work (STOPPING=1)
322345fdb9865ef2477fba8e4bdde0e1183ef505Lennart Poettering* verify that the AF_UNIX sockets of a service in the fs still exist
322345fdb9865ef2477fba8e4bdde0e1183ef505Lennart Poettering when we start a service in order to avoid confusion when a user
322345fdb9865ef2477fba8e4bdde0e1183ef505Lennart Poettering assumes starting a service is enough to make it accessible

322345fdb9865ef2477fba8e4bdde0e1183ef505Lennart Poettering the kernel cmdline. Right now setting one resets also the other.

* teach dbus to activate all services it finds in /etc/systemd/services/org-*.service
* support systemd.mask= on the kernel command line.
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commit;h=99ee5315dac6211e972fa3f23bcc9a0343ff58c4
* read config fragments for all units from /lib/systemd/system/foobar.service.d/ to override/extend specific settings
* port over to LISTEN_FDS/LISTEN_PID:
- rpcbind (/var/run/rpcbind.sock!) HAVEPATCH
- libvirtd (/var/run/libvirt/libvirt-sock-ro)
- allow specification of socket mode/umask when allocating DBusServer
* gnome-shell python script/glxinfo/is-accelerated must die
* patch kernel for xattr support in /dev, /proc/, /sys and /sys/fs/cgroup?
* set_put(), hashmap_put() return values check. i.e. == 0 doesn't free()!
