[Bug 1225518] Re: upstart doesn’t start sh on first run, starts on subsequent runs

[Artyom Kazak]

Strangely enough, a possible workaround is to wrap “exec…” in “script …
end script”.

Title:
  upstart doesn’t start sh on first run, starts on subsequent runs

Status in “upstart” package in Ubuntu:
  New

Bug description:
  Here’s an Upstart job, saved as /etc/init/r2.conf:

      setuid rtorrent
      exec screen -S rtorrent -fn -Dm rtorrent -n -o import=/tmp/rtconf

  (rtorrent and screen are available from Ubuntu repositories.)

  The first time I start it, everything is fine:

    # touch /tmp/rtconf    <-- creating empty config; needed only once

    # service r2 start
    r2 start/running, process 1007

    # ps aux | grep rtorrent
    rtorrent  1007  0.0  0.3  24132  1520 ?        Ss   20:13   0:00 SCREEN -S rtorrent -fn -Dm rtorrent -n -o import=/tmp/rtconf
    rtorrent  1008  0.2  1.2 262016  6388 pts/1    Ssl+ 20:13   0:00 rtorrent -n -o import=/tmp/rtconf

    # service r2 stop
    r2 stop/waiting

    # ps aux | grep rtorrent
    <nothing>

  However, when I start it for the second time, “sh” appears from
  nowhere:

    # service r2 start
    r2 start/running, process 1021

    # ps aux | grep rtorrent
    rtorrent  1021  0.0  0.1   4436   628 ?        Ss   20:14   0:00 /bin/sh -e -c screen -S rtorrent -fn -Dm rtorrent -n -o import=/tmp/rtconf /bin/sh
    rtorrent  1022  0.0  0.3  24132  1524 ?        Ss   20:14   0:00 SCREEN -S rtorrent -fn -Dm rtorrent -n -o import=/tmp/rtconf
    rtorrent  1023  0.0  1.2 262016  6428 pts/2    Ssl+ 20:14   0:00 rtorrent -n -o import=/tmp/rtconf

  What’s worse, due to this it doesn’t stop as expected:

    # service r2 stop
    r2 stop/waiting

    # ps aux | grep rtorrent
    rtorrent  1022  0.0  0.3  24132  1524 ?        Ss   20:14   0:00 SCREEN -S rtorrent -fn -Dm rtorrent -n -o import=/tmp/rtconf
    rtorrent  1023  0.0  1.2 262016  6428 pts/2    Ssl+ 20:14   0:00 rtorrent -n -o import=/tmp/rtconf

  The version of Ubuntu I’m using is 13.04 x64. The version of Upstart
  is 1.8-0ubuntu1.
