Description Zdenek Pytela 2017-01-17 13:01:01 UTC
Created attachment 1241770 [details]
strace of systemctl is-enabled iscsi

Description of problem:
Under some conditions, systemctl reports an error on a nonexisting service unit, but exits with exit status 0. Therefore also subsequent actions based on exit status fail. It happens during a kickstart update with selinux enforcing, most likely only when selinux-policy package is updated.

Version-Release number of selected component (if applicable):
systemd-219-30.el7_3.6.x86_64

How reproducible:
always on customer's site

Steps to Reproduce:
1. On a satellite server, prepare updates to deploy.
2. Add setenforce 1 to %post section
3. Execute
systemctl is-enabled nonexisting; echo $?

Actual results:
Failed to get unit file state for nonexisting.service: No such file or directory
0

Expected results:
Failed to get unit file state for nonexisting.service: No such file or directory
1


Additional info:
Not sure if it is relevant, but the current working theory is that it happens only when selinux-policy package is part of the update suite. Additionally, after leaving the chrooted environment, no command can be run any longer. A known workaround is to execute setenforce 0.
