The build section lists commands to run as part of the build process This is where you can use a root/createlinks script to create events and action links. see

%build
perl createlinks

Example 1

#!/usr/bin/perl -w

sub safe_symlink {
   my ($from, $to) = @_;
   use File::Basename;
   use File::Path;
   mkpath(dirname($to));
   unlink($to);
   symlink($from, $to) or die "Can't create symlink from $from to $to: $!";
}
sub panel_link

{
 my ($function, $panel) = @_;
    safe_symlink("../../../functions/$function",
         "root/etc/e-smith/web/panels/$panel/cgi-bin/$function");
}
sub event_link

{

   my ($action, $event, $level) = @_;
    safe_symlink("../actions/${action}",
               "root/etc/e-smith/events/${event}/S${level}${action}");
}
 #--------------------------------------------------
 # functions for manager panel
 #--------------------------------------------------
panel_link("yum", "manager");

   #--------------------------------------------------
   # actions for yum-update event
   #--------------------------------------------------
event_link("initialize-default-databases", "yum-update", "10");
event_link("conf-yum", "yum-update", "20");
event_link("yum-arch-repository", "yum-update", "30");
event_link("yum-check-repository", "yum-update", "40");

Example 2 : Sme8admin

#! /usr/bin/perl -w

use esmith::Build::CreateLinks qw(:all);

# Start and stop links
service_link_enhanced("sme8admind", "S99", "7");
service_link_enhanced("sme8admind", "K97", "6");
service_link_enhanced("sme8admind", "K20", "0");
service_link_enhanced("sme8admind", "K20", "1");

# Links for the panel
panel_link("sme8admin", "manager");
#system("mkdir -p root/etc/e-smith/web/panels/manager/html/sme8admin");
safe_symlink("/etc/e-smith/web/panels/manager/html/sme8admin", "root/etc/e-smith/web/panels/user/html/sme8admin");

# Logrotate
event_link("sme8admin-parselog","logrotate","15");
