Package: lsb-base
Version: 9.20161125
Apparently pidofproc returns the PIDs of programs running
in a chroot or in a container, if there is no local PID file.
This is a *huge* problem for me, because either the init
scripts on the host fail to restart services, or they affect
services running in a container/chroot.
Sample session:
root@mydb01a:~# . /lib/lsb/init-functions
root@mydb01a:~# pidofproc /usr/sbin/smtpd
26623
root@mydb01a:~# ps -ef | grep smtp[d]

Please note the smtpds running in 2 LXC containers. If I kill
the local smtpd, then pidofproc finds the foreign smtpds:
root@mydb01a:~# kill 26623
root@mydb01a:~# pidofproc /usr/sbin/smtpd
4199 4198 4197 4196 4195 4194 4193 1695 1694 1693 1692 1691 1690 1689
root@mydb01a:~# echo $?
0
If pidofproc would use "pidof -c" internally, then it should work as
expected:
root@mydb01a:~# /bin/pidof -o %PPID -x /usr/sbin/smtpd
4199 4198 4197 4196 4195 4194 4193 1695 1694 1693 1692 1691 1690 1689
root@mydb01a:~# /bin/pidof -c -o %PPID -x /usr/sbin/smtpd
root@mydb01a:~# echo $?
1
lsb-base version 9.20170808 has the same problem. I would highly
appreciate a fix for stretch and sid.

Harri
