wrong database file ownership

[Francois Trahan]

ubuntu 13.10 amd64
vnstat 1.11-2

Problem:
Database files created by "vnstat -u -i NEW_IF" (/var/lib/vnstat/NEW_IF) are owned by root, the vnstat user cannot write to them.

Symptoms:
After adding a database, you always get the "Not enough data available yet." even if vnstat works perfectly in live mode (vnstat -i NEW_IF -l)

Workaround:
Run those commands:
- chown vnstat:vnstat /var/lib/vnstat/NEW_IF
- vnstat -u -i NEW_IF

with vnstat 1.12 (as in 14.10 and later) vnstat changes the user id during startup to whatever is defined as DaemonGroup and DaemonUser in /etc/vnstat.conf. Hence, the proper way would be to
(0) upgrade to vnstat 1.12 (if not already done)
(1) change in /etc/vnstat.conf DaemonUser and DaemonGroup from "" to "vnstat", and
(2) in /lib/systemd/system/vnstat.service or /etc/init.d/vnstat depending on start-up system user from "vnstat" to "root"

Status changed to 'Confirmed' because the bug affects multiple users.
