Description Jan Stodola 2011-06-15 09:02:19 UTC
Description of problem:
Following message is written in /root/install.log after installation of F15:

...
Installing kbd-1.15.2-2.fc15.x86_64
Installing systemd-26-1.fc15.x86_64
/bin/grep: /etc/pam.d/system-auth-ac: No such file or directory
Installing linux-firmware-20110304-1.fc15.noarch
...

[root@gilliam ~]# rpm -q --scripts systemd
postinstall scriptlet (using /bin/sh):
/bin/systemd-machine-id-setup > /dev/null 2>&1 || :
/bin/systemctl daemon-reexec > /dev/null 2>&1 || :

# Make sure pam_systemd is enabled
if ! /bin/grep -q pam_systemd /etc/pam.d/system-auth-ac ; then
        /usr/sbin/authconfig --update >/dev/null 2>&1 || :

        # Try harder
        /bin/grep -q pam_systemd /etc/pam.d/system-auth-ac || /usr/sbin/authconfig --updateall >/dev/null 2>&1 || :
fi


There should be some check whether the file exists before running 'grep' on it.


Version-Release number of selected component (if applicable):
systemd-26-1.fc15.x86_64

How reproducible:
always

Steps to Reproduce:
1. install F15 with default package set
2. check /root/install.log for errors

  
Actual results:
Error message during installation:
/bin/grep: /etc/pam.d/system-auth-ac: No such file or directory


Expected results:
no error messages

Comment 1 Michal Schmidt 2011-06-15 10:24:48 UTC
Is the file /etc/pam.d/system-auth-ac present after the installation?
Does it contain this line?:
  -session     optional      pam_systemd.so

If yes, then everything is alright and we just should shut up the message.
It does not really matter whether we do that by checking for the existence first or by redirecting stderr to /dev/null.

Comment 2 Jan Stodola 2011-06-15 10:51:24 UTC
Yes, the file is present:

[root@gilliam ~]# grep pam_systemd.so /etc/pam.d/system-auth-ac
-session     optional      pam_systemd.so
[root@gilliam ~]#

Comment 3 Göran Uddeborg 2011-07-05 21:32:38 UTC
I got the same message when I made a "yum --installroot ... groupinstall Base" to create a diskless client.

The file system-auth-ac belongs to the authconfig package, but only as %ghost:s.  And there isn't any scripts in the authconfig package that would create them.

Throwing away the message would silence RPM, but maybe a cleaner solution would be to explicitly test for the file's existence?

if ! test -f /etc/pam.d/system-auth-ac || ! /bin/grep -q pam_systemd /etc/pam.d/system-auth-ac ; then

Reproduced in f16 with systemd-33-1.fc16.x86_64

Comment 7 Mads Kiilerich 2011-09-02 15:19:52 UTC
_not_ fixed by systemd-35-1.

It runs
  /bin/grep -q pam_systemd /etc/pam.d/system-auth-ac
but that will scream and fail too.

Comment 8 Matthias Runge 2011-09-07 07:30:54 UTC
is this a bug in authconfig (file is not there, but should be) or a bug in systemd's post-install?

[mrunge@herodot pam.d]$ /bin/grep -q pam_systemd /etc/pam.d/system-auth-ac 
[mrunge@herodot pam.d]$ 

No output, no screaming. Does it mean, it's fixed?

Comment 9 Mads Kiilerich 2011-09-07 09:10:03 UTC
/etc/pam.d/system-auth-ac is a %ghost file owned by authconfig. It do not exist when systems are installed in chroots, but it will probably be created by anaconda/firstboot and will thus always exist on running systems and on updates.

So there is a "contract inconsistency" between systemd and authconfig, and the most obvious place to fix it would be systemd.

Comment 10 Fedora Update System 2011-09-09 17:06:52 UTC
systemd-35-1.fc16 has been pushed to the Fedora 16 stable repository.  If problems still persist, please make note of it in this bug report.
