problems with systemd

[ben thielsen]

unfortunately, yet another example of a package that is now broken thanks to ubuntu switching to systemd. the /etc/defaults/ settings are no longer honored:

>cat /etc/default/haveged
# Configuration file for haveged

# Options to pass to haveged:
# -w sets low entropy watermark (in bits)
#DAEMON_ARGS="-w 1024"
DAEMON_ARGS="-w 4000"

>ps -Aefd | grep -iF haveged
root 446 1 0 Feb01 ? 00:00:02 /usr/sbin/haveged --Foreground --verbose=1 --write=1024

this setting appears to now be hard coded:
>cat /lib/systemd/system/haveged.service
[Unit]
Description=Entropy daemon using the HAVEGE algorithm
Documentation=man:haveged(8) http://www.issihosts.com/haveged/

[Service]
ExecStart=/usr/sbin/haveged --Foreground --verbose=1 --write=1024

[Install]
WantedBy=default.target

having to modify this file manually to change this setting feels like a step backwards.

1] >lsb_release -rd
Description: Ubuntu 15.10
Release: 15.10

2] >apt-cache policy haveged
haveged:
  Installed: 1.9.1-1
  Candidate: 1.9.1-1
  Version table:
 *** 1.9.1-1 0
        500 http://us.archive.ubuntu.com/ubuntu/ wily/universe amd64 Packages
        100 /var/lib/dpkg/status

3] i expected the init system to honor settings which had previously been defined
4] it did not
