Description Mike Holden 2011-09-30 19:16:59 UTC

Description of problem:
Startup entries in /etc/rcd.0-6 are removed when updating the package version. This means that after the next reboot, unless you remember to chkconfig postfix on, your MTA doesn't start up after the next reboot.

Version-Release number of selected component (if applicable):
postfix-2.7.5-1.fc14.x86_64 (although this has been the case for the last few updates before that).

How reproducible:
100%

Steps to Reproduce:
1. chkconfig --list postfix
2. yum upgrade postfix
3. chkconfig --list postfix
  
Actual results:
1. postfix        	0:off	1:off	2:on	3:on	4:on	5:on	6:off
3. postfix        	0:off	1:off	2:off	3:off	4:off	5:off	6:off


Expected results:
1. postfix        	0:off	1:off	2:on	3:on	4:on	5:on	6:off
3. postfix        	0:off	1:off	2:on	3:on	4:on	5:on	6:off

F14 is EOL. I checked on F15 and I was unable to reproduce. From f16 and up postfix was switched to systemd unit file. The problem could be caused by wrong alternatives settings. I did on F15:

# alternatives --config mta
# chkconfig --list postfix
Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

postfix        	0:off	1:off	2:on	3:on	4:on	5:on	6:off
# yum upgrade postfix
# chkconfig --list postfix

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

postfix        	0:off	1:off	2:on	3:on	4:on	5:on	6:off

Thus I am closing this as works for me. If the problem persists feel free to reopen.

Comment 2 Mike Holden 2012-07-05 20:02:20 UTC

I've now upgraded to F16, and guess what, aster upgrading postfix, it was again removed from startup, so I had no mail after a reboot. Either something is screwy, or I'm doing something wrong?

chkconfig show the following, showing that it is now a systemd service, no problem with that:

[root@jewel ~]# chkconfig --list postfix

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

service postfix supports chkconfig, but is not referenced in any runlevel (run 'chkconfig --add postfix')

However:

[root@jewel ~]# systemctl status postfix.service
postfix.service - LSB: start and stop postfix
          Loaded: loaded (/etc/rc.d/init.d/postfix)
          Active: active (running) since Tue, 03 Jul 2012 23:15:46 +0100; 1 day and 21h ago
        Main PID: 10079 (master)
          CGroup: name=systemd:/system/postfix.service
                  ├ 10079 /usr/libexec/postfix/master
                  ├ 10082 qmgr -l -t fifo -u
                  └ 23867 pickup -l -t fifo -u
[root@jewel ~]# systemctl enable postfix.service
postfix.service is not a native service, redirecting to /sbin/chkconfig.
Executing /sbin/chkconfig postfix on
[root@jewel ~]# !chkc
chkconfig --list postfix

Note: This output shows SysV services only and does not include native
      systemd services. SysV configuration data might be overridden by native
      systemd configuration.

postfix         0:off   1:off   2:on    3:on    4:on    5:on    6:off

This output seems to imply that it isn't a systemd service either, so it calls back to chkconfig to enable it.

Is there sendmail or another MTA installed? If yes, you need to switch the postfix to be your default MTA via alternatives, otherwise the postfix will be switched off during updates, e.g.:

# alternatives --config mta
and select postfix. Verify with:

# alternatives --display mta
There should be:
mta - status is manual.
 link currently points to /usr/sbin/sendmail.postfix
...

Sure, it was converted to native systemd in f17.

Comment 4 Mike Holden 2012-07-10 17:40:19 UTC

That would appear to be the issue. It was set for sendmail. I guess I find out next time I upgrade postfix!

Comment 5 Jaroslav Škarvada 2012-07-11 06:28:42 UTC

Thanks for info, closing as notabug for now. Feel free to reopen if the issue persists.
