   42 <h1>Coolnesses of the Arusha Project</h1>
   43 
   44 Our old friend Sigbjorn Finne used to say, ``The
   45 coolness-to-usefulness ratio must always be greater than
   46 one.''  The Arusha Project (ARK) passes this test, easily.
   47 <p>
   48 (Disclaimer: the current ARK code doesn't do all of this
   49 cool stuff.  The point is, the ARK framework and way of
   50 thinking will make this stuff possible.)
   51 <p>
   52 <ul>
   53 <li><em>One command</em> builds all packages for all platforms at
   54 a site:
   55 <pre>
   56 % ark package reveal ALL
   57 </pre>
   58 <li>
   59 A ``package'' that is your own sendmail config is handled
   60 the same way as a package that is the FlexLM
   61 license manager, which is handled the same way
   62 as an open-source package:
   63 <pre>
   64 % ark package deploy sendmail-config flexlm--6.02 apache--2.0.45
   65 </pre>
   66 <li>
   67 You can have multiple versions of a package active at once:
   68 <pre>
   69 % ark package reveal xemacs--21.4.12 xemacs--21.5.11
   70 </pre>
   71 <li>
   72 Whether a package is local to a host, or whether a single
   73 copy is shared among many hosts (e.g. by NFS) is completely configurable,
   74 and managed automatically.
   75 <p>
   76 <li>
   77 Hosts, users, ``disk chunks'', web sites, etc., can be
   78 handled within <em>one framework</em>; so...
   79 <pre>
   80 % ark user create fourth-year-class
   81 % ark host verify sparc-solaris7
   82 </pre>
   83 <li>
   84 If you have ``at boot time'' actions associated with packages,
   85 users, web sites, etc., they can all be done (in the right
   86 order) with:
   87 <pre>
   88 # ark package  at-boot --hosts=. --quiet ALL
   89 # ark user     at-boot --hosts=. --quiet ALL
   90 # ark website  at-boot --hosts=. --quiet ALL
   91 </pre>
   92 (Similarly for ``at shutdown time'', and much the same for
   93 regular tasks to be done by `cron'...)
   94 <p>
   95 <li>
   96 Most importantly, you can <strong>collaborate</strong> with
   97 like-minded sysadmins (in `teams') on the stuff you agree about!
   98 If, for example, you agree with how team Sidai does
   99 Apache, then your total configuration effort might be:
  100 <pre>
  101 &lt;package name="apache--2.0.45" xml-version="1"&gt;
  102 &lt;status&gt;revealed&lt;/status&gt;
  103 &lt;prototypes&gt;
  104   &lt;prototype team="sidai" name="apache"/&gt;
  105   &lt;prototype team="." 	  name="ALL"/&gt;
  106 &lt;/prototypes&gt;
  107 &lt;hosts-supported&gt;&lt;list&gt;
  108   &lt;item&gt;sparc-solaris-web-server&lt;/item&gt;
  109 &lt;/list&gt;&lt;/hosts-supported&gt;
  110 &lt;/package&gt;
  111 </pre>
  112 If, however, you disagreed with the Sidai folks on the
  113 `install-bits' method, you would simply
  114 override theirs by adding to the above:
  115 <pre>
  116 &lt;install-bits&gt;
  117 &lt;code&gt;&lt;![CDATA[
  118 # your code here: shell, Python, or Perl script
  119 ]]&gt;&lt;/code&gt;&lt;/method&gt;
  120 &lt;/install-bits&gt;
  121 </pre>
  122 </ul>
  123 <p>
  124 <strong>ToDo: the rest</strong>
