Bespoke services: application/catman

For various reasons—some reasonable, some suspect—Solaris doesn’t ship with a compiled set of windex databases for its manual pages. The unfortunate result is that helpful commands like apropos(1) or man -k are unhelpful:

$ apropos sort
/usr/man/windex: No such file or directory

smf(5) provides one way to address this shortcoming, via a transient service to be run during startup. Our service description would be roughly equivalent to the following:

<?xml version="1.0"?>
<!DOCTYPE service_bundle SYSTEM "/usr/share/lib/xml/dtd/service_bundle.dtd.1">
<service_bundle type='manifest' name='sch:catman'>
<service
  name='application/catman'
  type='service'
  version='1'>
<create_default_instance enabled='false' />
<single_instance />
<!--
  By default, application/catman will run in the background
  during boot.  If you want to run it periodically, execute</p>

    /usr/sbin/svcadm restart catman

  If you wish to augment the default MANPATH, use the setenv
  subcommand to svccfg(1M).  For instance, to add the Java
  manual pages to the build:

    /usr/sbin/svccfg -s application/catman
    > setenv MANPATH /usr/share/man:/usr/java/man
    > exit
    /usr/sbin/svcadm refresh catman

  If MANPATH is not defined, the default manual path is
  /usr/share/man, as per catman(1M).

      section='1M'
      manpath='/usr/share/man' />
  </documentation>
</template>
</service>
</service_bundle>

Following my own instructions in the comment block, I defined a value for MANPATH and refreshed the service. My setting can be double-checked with svcprop(1) like so:

$ svcprop -p start application/catman
start/exec astring /usr/bin/catman\ -w
start/timeout_seconds count 0
start/type astring method
start/environment astring MANPATH=/usr/share/man:/usr/openwin/man:/usr/sfw/man:/usr/dt/man:/usr/perl5/man:/usr/java/man:/usr/apache/man:/usr/X11/man:/opt/sfw/man:/opt/csw/man

Issuing “svcadm enable catman” will cause the service to be executed immediately, and upon each subsequent boot. Our earlier query becomes fecund:

Exercises

1. Add a configuration property that makes the service also rebuild the nroffed versions of the manual pages, if set to true.
2. Make the service regenerate only in the case that components in the path have changed.
