Restarting inetd picks up environment, passed on via telnet

Curious problem I just encountered: needing to restart inetd, I su'd to root and executed the usual commands

Code:

# /etc/init.d/inetsvc stop
# /etc/init.d/inetsvc start

Shortly after this, users started reporting unexpected behaviour after logging in with telnet, and it turned out they all had environment variables set to values that only I would use.

It appears (at least, this is the only explanation I have been able to come up with) that inetd inherited my environment (carried over via su) when I executed the 'inetsvc start' script, and telnet, and thence the login shell, then also inherited that environment.

Has anyone else noticed this? Is this a bug? Or should I have restarted the service some other way?

started

started(7)						 Miscellaneous Information Manual						started(7)

NAME

       started - event signalling that a job is running

SYNOPSIS

       started JOB=JOB INSTANCE=INSTANCE [ENV]...

DESCRIPTION

       The  started  event is generated by the Upstart init(8) daemon when an instance of a job has finished starting and is now running.  The JOB
       environment variable contains the job name, and the INSTANCE environment variable contains the instance name which will be empty  for  sin-
       gle-instance jobs.

       init(8)	emits this event as an informational signal, services and tasks started or stopped by this event will do so in parallel with other
       activity.  It is typically combined with the stopping(7) event by services declaring a dependency.

       Job configuration files may use the export stanza to export environment variables from their own environment into the started  event.   See
       init(5) for more details.

EXAMPLE

       A service that wishes to depend on another service might use:

	      start on started apache
	      stop on stopping apache

       A task that must be run after another task or service has been started might use:

	      start on started postgresql
