Dear maintainer(s) of mate-screensaver,

it appears that mate-screensaver 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 mate-screensaver
  that use `pidof` at runtime;
* via the `Build-Depends:` field of mate-screensaver, 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 mate-screensaver, 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 mate-screensaver uses `pidof` due to the following
code snippets:

```
path: mate-screensaver_1.26.2-1/src/gs-lock-plug.c
{
        int num_processes;
        gchar *command = g_strdup_printf ("pidof %s | wc -l", name);
        FILE *fp = popen(command, "r");
```

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

This code is a duplicate of what is found in mate-session-manager (see
<https://bugs.debian.org/1136529>), so the same resolution applies: the
package must depend on procps.

A MR that adds procps as a dependency can be found at
<https://salsa.debian.org/debian-mate-team/mate-screensaver/-/merge_requests/2>.
