Dear maintainer(s) of acpi-support,

it appears that acpi-support uses `pidof` in its testsuite, or that
at least one of its binary packages uses `pidof` at runtime.
Historically, `pidof` was provided by the Essential package
`sysvinit-tools`, making an explicit dependency unnecessary. However
`pidof` will soon be moved to `procps` and will no longer be part of
the Essential set.

Please add an explicit dependency on `procps`:

* via the `Depends:` field of all binary packages of acpi-support
  that use `pidof` at runtime;
* via the `Build-Depends:` field of acpi-support, if `pidof` is
  used in tests run at build-time;
* via the `Depends:` field of `debian/control/tests`, if `pidof` is
  used in autopkgtests.

To prevent any disruption for users of acpi-support, please add
this dependency now, before `pidof` is moved from `sysvinit-utils` to
`procps`. Alternatively, you could remove all uses of `pidof`.

It is believed that acpi-support uses `pidof` due to the following
code snippets:

```

	if [ x$LOCK_SCREEN = xtrue ]; then
		if pidof xscreensaver >/dev/null; then
			su "$XUSER" -s /bin/sh -c "xscreensaver-command -lock"
		elif pidof gnome-screensaver > /dev/null; then

	fi

if pidof xscreensaver > /dev/null; then
    d=/tmp/.X11-unix
    for x in $d/*; do

	pidof -x $PMS > /dev/null ||
        PowerDevilRunning ||
	GnomeSettingsDaemonPowerRunning
```

Feel free to close this issue if this is a false positive (for example
if this code is in an unreachable code path).
