[Launchpad Bug Tracker <1413699@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug:

'pgrep upstart-udev-bridge' should definitely spit out a pid, but it
doesn't. When one uses the option -f than it actually prints the PID of
the upstart-udev-bridge process. However using -f is a bad workaround,
because than (at least wrt. the man page) the arguments and operands get
included into the match, which may break scripts or even lead to
security issues.

I guess, the bug is, that p{grep|kill} strips off everything after the
first '-' of the command before it actually tries to compare with the
given operand (or something like that).
