Package: haveged Version: 1.9.1-1 Severity: Important haveged(8) is not honoring the DAEMON_ARGS variable in /etc/default/haveged when the init system is systmed(8). This is due to the following configuration file:
$ cat /etc/systemd/system/default.target.wants/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
Setting the "write_wakeup_threshold" in /etc/default/haveged to 4096, instead
of the default 1024, it should be reflected when restarting the daemon, but
seems to still be setting the default to 1024 per systemd(8):
$ grep DAEMON_ARGS /etc/default/haveged
DAEMON_ARGS="-w 4096"
$ sudo /etc/init.d/haveged restart
[ ok ] Restarting haveged (via systemctl): haveged.service.
$ ps -ef | grep 'havege[d]'
root 458 1 0 10:30 ? 00:00:00 /usr/sbin/haveged
--Foreground --verbose=1 --write=1024
Changing the /etc/systemd/system/default.target.wants/haveged.service config
file to set the write_wakeup_threshold to 4096 fixes this. So, either the
/etc/default/haveged config file is no longer necessary with systemd(8), or a
bug exists such that it should be overwriting the entries in
/etc/systemd/system/default.target.wants/haveged.service, but is not.
Thanks,
