Beowulf - new stuff

Having installed Beowulf, I notice that there are some new daemons some of which I don't recognise. These include :-

/usr/sbin/dundee
/usr/sbin/ofonod
/usr/sbin/connmand
/usr/sbin/bluetoothd

and in my name :-

/usr/lib/geoclue-2.0/demos/agent
/usr/bin/qlipper

connman is the new network connection manager, although I don't have much to manage, just the wired ether.
bluetooth; my desktop does not have bluetooth hardware and so I can disable that.
dundee does not have a man page and I have not found anything about it yet on the net. /etc/init.d/dundee says that it is a Bluetooth DUN daemon, which I think is for DialUp Networking.
ofonod is an oFono mobile telephony daemon, according to "man ofonod". Some Ubuntu docs report that it is responsible for the mobile telephony part and bluetoothd uses it to place and answer phone calls.

geoclue works out where you are, using WiFi, GPS, 3G etc. Brought in by LXQt.
qlipper is a clipboard history applet, brought in by LXQt.

dmesg also reports that AppArmor is enabled. There is some info at :-

https://wiki.debian.org/AppArmor/HowToUse

Adding "Z" to "ps" shows the Labels. Most things are "unconfined", but if you run LibreOffice then
ps axjfZ includes :-

Re: Beowulf - new stuff

Another entry in daemon.log is for haveged. From /etc/init.d/haveged the description is :-

haveged uses HAVEGE (HArdware Volatile Entropy Gathering and Expansion)
 to maintain a pool of random bytes used to fill /dev/random whenever necessary.

This daemon appears to start but I cannot see it running and there are no error messages.

/etc/init.d/haveged status
[FAIL] haveged is not running ... failed!
