The init script fails if another process has the word "telegraf" in
it, for example if you aren running "vi /etc/opt/telegraf/telegraf.conf"
or "tail -f /var/log/telegraf/telegraf.log". This is because
the "-f" flag to "pgrep" will show processes with the search
string anywhere in the command-line.
This patch turns it around and gets the "ps" output for the process
in the pidfile, and if that line has "telegraf" in it, it considers
it to be running.
Closes#266Closes#267
The test to see which version of `useradd` is installed uses 'bashisms'
that fail on Ubuntu due to the fact that `/bin/sh` is symlinked to Dash,
causing the telegraf account to be created without the `--system` option
ever being passed.
This change amends the syntax so that it's POSIX-compatible and more
portable as a result.
