Hello,

Following a change in the config file of a program, I'd like to display a message to my users to indicate they need to update the config file with the new one. I try "echo" in the update scriptlet:

%postun
if [ "$1" -ge "1" ] ; then # Upgrade
  dnscrypt-proxy -service install --config %{_sysconfdir}/dnscrypt-proxy/dnscrypt-proxy.toml   echo 'Since version 2.0.45, some of the configuration files have been renamed.   Please merge your config to /etc/dnscrypt-proxy/dnscrypt-proxy.toml.rpmnew then
   replace dnscrypt-proxy.toml with that file.
  Read /usr/share/doc/dnscrypt-proxy/ChangeLog to merge files accordingly.'
fi

But it doesn't work as expected. Is there a way to transmit that message to my users?

The automatic message about the saving of the new configuration as an *.rpmnew file should tell any sysadmins that the configuration needs to be revised.

If the service doesn't works fine with the old configuration. Maybe you could add a service ExecStartPre script that fails with a pretty message about the file migration required.



Best regards,
