RHEL 7 systemd scripts which is not the case with Bug #1078829

So I'm going to close this bz since is very unlikely the 
same problem exists.

Steve,

'nfs-utils' restarts the NFS daemons too:

# rpm -q nfs-utils
nfs-utils-1.3.0-0.8.el7.x86_64

# rpm -q --scripts nfs-utils
[...]
postuninstall scriptlet (using /bin/sh):

/usr/bin/systemctl daemon-reload >/dev/null 2>&1 || : 
if [ $1 -ge 1 ] ; then 
        # Package upgrade, not uninstall 
        /usr/bin/systemctl try-restart nfs-client.target >/dev/null 2>&1 || : 
fi 

/usr/bin/systemctl daemon-reload >/dev/null 2>&1 || : 
if [ $1 -ge 1 ] ; then 
        # Package upgrade, not uninstall 
        /usr/bin/systemctl try-restart nfs-server >/dev/null 2>&1 || : 
fi 

So I'm afraid that the problem exists in RHEL 7 too.

Fine...
Comment 8 Yongcheng Yang 2015-08-05 06:50:44 UTC 
It seems RHEL7 not act the same with RHEL6:

1. The configure file name for RHEL 7 is "nfs-utils-disable-postun", but it's "nfs-utils-disable-posttrans" for RHEL6;

2. Seems the exports configuration will NOT lost while updating the nfs-utils package, no matter file "/etc/sysconfig/nfs-utils-disable-posttrans" exist or not.

So are these current behavior all right or not?

Comment 19 Yongcheng Yang 2015-08-11 00:45:59 UTC 
Verified with nfs-utils-1.3.0-0.11.el7.x86_64
And the different configure file name of RHEL-7 (nfs-utils-disable-postun) with RHEL-6 (nfs-utils-disable-posttrans) maybe not a problem.
