Apply DNS to all the Linux servers (minions) using SaltStack

Okey, let's say you want to change nameserver preferences of about 25 Linux servers. You can do it one by one or take a breath and try SaltStack. 1. In your salt master, create a folder name dns ( /srv/salt/dns ) 2. In /srv/salt/dns/ create: * init.sls : /etc/resolv.conf:   file.managed:     - source: salt://dns/resolv.conf     - user: root     - group: root     - mode: 644     - template: jinja /etc/resolvconf/resolv.conf.d/original:   file.managed:     - source: salt://dns/original     - user: root     - group: root     - mode: 644     - template: jinja * resolv.conf : # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8) #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN nameserver my.dns.server1 nameserver my.dns.server2 search my.domain.com * original : search my.domain.com nameserver my.dns.server1 nameserver my.dns.server2 3. Run this salt command: # salt '*' state.sls dns

Open the special_pagerestrictions.php file (at /path/to/your/dekiwiki/deki/plugins/special_page/special_pagerestrictions/ ) using nano or any text editor you like 2. Modify this code block with the red line: var itemSelectHandler = function(sType, aArgs) {         var oAcInstance = aArgs[0];         var oData = aArgs[2];           if ( oData && oData[0] )         {                 oAcInstance._elTextbox.value = Deki.$.htmlDecode(oData[1] ? oData[1] : oData[0]);                 jQuery("#autoCompInput").val(
