Description Kaushik Banerjee 2013-11-21 13:16:04 UTC 
Description of problem:
systemctl stop <service> doesn't kill daemons started from cmdline.

This is probably a feature in systemd. Logging this as a bug to see if this can be documented, since this is a change in behaviour from RHEL6.

Version-Release number of selected component (if applicable):
systemd-207-2.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. sssd -d 9 -f -c /tmp/sssd.conf

2. # systemctl stop sssd.service
# ps ax | grep sssd
18140 ?        Ss     0:00 sssd -d 9 -f -c /tmp/sssd.conf
18141 ?        S      0:00 /usr/libexec/sssd/sssd_be --domain LDAPTEST -d 0x77f0 --debug-to-files
18142 ?        S      0:00 /usr/libexec/sssd/sssd_nss -d 0x77f0 --debug-to-files
18143 ?        S      0:00 /usr/libexec/sssd/sssd_pam -d 0x77f0 --debug-to-files

3. # systemctl restart sssd.service
# ps ax | grep sssd
18140 ?        Ss     0:00 sssd -d 9 -f -c /tmp/sssd.conf
18141 ?        S      0:00 /usr/libexec/sssd/sssd_be --domain LDAPTEST -d 0x77f0 --debug-to-files
18142 ?        S      0:00 /usr/libexec/sssd/sssd_nss -d 0x77f0 --debug-to-files
18143 ?        S      0:00 /usr/libexec/sssd/sssd_pam -d 0x77f0 --debug-to-files
18333 ?        Ss     0:00 /usr/sbin/sssd -D -f
18334 ?        S      0:00 /usr/libexec/sssd/sssd_be --domain LDAPTEST --debug-to-files
18335 ?        S      0:00 /usr/libexec/sssd/sssd_nss --debug-to-files

Daemons forked off from a user's shell (and hence running in the user's session cgroup) are not "services" as such. See also bug 1021565, bug 990039.
Comment 3 Lukáš Nykrýn 2013-11-25 12:29:49 UTC 
Maybe this could be mentioned in documentation in differences between service in rhel6 and systemctl in rhel7. (But please note that service in rhel7 is just calling systemctl)

Thank you, I will document this in the chapter about systemd.
