One simple solution would be to define an array that maps service to process...
What I show below is a quick kludge (if /etc/init.d/bind fails, then try
/etc/init.d/bind9), but you could be neater and make something that uses
isvariable(). Or you could simply define an array element for *every* service,
and build your service slist by using getindices, and then just always use the
array values as the name of the file to reference...
vars:
"service" slist => { "ssh", "snmpd", "apache2", "bacula-fd", "denyhosts", };
"exception[bind]" string => "bind9";
commands:
"${daemon_path}/${service}"
comment => "Executing command '${daemon_path}/${service} start'",
ifvarclass => "${service}_up",
classes => if_notkept("$(service)_restart_failed"),
args => "restart";
"${daemon_path}/${exception[$(service)]}"
comment => "Executing exception command
'${daemon_path}/${exception[$(service)]} start'",
ifvarclass => "${service}_restart_failed",
args => "restart";
body classes if_notkept(x)
{
repair_failed => { "$(x)" };
repair_denied => { "$(x)" };
repair_timeout => { "$(x)" };
}
