Package: vnstat
Version: 1.12-2
Severity: important
Dear Maintainer,
On an Alix board without an RTC I am currently having trouble to get vnstat
running
on boot, I always get the following error:
-----
$ systemctl status vnstat
● vnstat.service - vnStat network traffic monitor
Loaded: loaded (/lib/systemd/system/vnstat.service; enabled)

Starting vnstat manually ("$ systemctl start vnstat") works as at that time NTP
has fetched
the correct time for me.
On embedded devices it is rather common to not have an RTC and with
ARM based devices running Debian on the rise, I thought I'd mark this
bug as "important".
I guess either vnstat should retry instead of exiting. And/or maybe the
neat, new dependancy system available thanks to systemd could be used.
The mysqld unit does something like that, e.g. units depending on it
will be started not after mysqld has started, but once mysqld reports
being ready to receive queries. This is done through
"ExecStartPost=/usr/libexec/mysqld-wait-ready" in the mysqld unit.
Maybe something like that could be done with NTP and vnstat too?
A quick and dirty solution would be to simply add the line "Restart=on-failure"
to the vnstat unit, I guess.
Regards, Linus
