Bug#472846: busybox: Regression in pidof: no longer lists 'debian-installer' processes

[Frans Pop <elendil@planet.nl>]

Package: busybox
Version: 1:1.9.2-1
Severity: important
Tags: d-i

In Debian Installer we're seeing a regression in pidof. For certain
processes it no longer returns the PID.

# ps ax | grep [d]ebian-installer
  452 root       1408 S   /bin/sh /sbin/debian-installer
 5594 root       1964 S   /bin/sh /sbin/debian-installer /bin/network-console-m
 5641 root       1964 S   /bin/sh /sbin/debian-installer /bin/network-console-m
# pidof debian-installer
#

With busybox 1.3.x the pidof command would return the PIDs:
# pidof debian-installer
452 5594 5641


The first of these processes is started from /etc/inittab:
::respawn:/bin/cttyhack /sbin/debian-installer

The second and third are started from an ssh connection to the system:
# cat /etc/passwd
root:*:0:0:root:/:/bin/sh
installer:x:0:0:installer:/:/bin/network-console
# cat /bin/network-console
#!/bin/sh
set -e
[...]
exec /sbin/debian-installer /bin/network-console-menu
