I'm working an a bundle for Apache, and specifically the processes:
section. I have several conditions:
* If httpd not running, start it.
* If httpd not running as root/apache, kill current processes, and start
the daemon properly.
* If there are "too few" httpd processes (i.e. 1-2), kill them, and
restart.
As best I can figure, this requires three separate promises, and at
least two more bodies in support. Am I completely missing a simpler
solution here?

bundle httpd {
processes:
Webservers::
"/usr/sbin/httpd"
process_count => httpd_stragglers,
signals => { 'term', 'quit', 'kill' },
comment => "Kill off stragglers: if only 1 or 3 procs
present, it's probably broken.";
"/usr/sbin/httpd"
process_select => not_apache_user,
signals => { 'term', 'quit', 'kill' },
comment => "Kill off httpd processes not owned by either
'root' or 'apache'";
"/usr/sbin/httpd"
restart_class => "StartHTTPD",
comment => "Start apache if it isn't running";
}
body process_count httpd_stragglers {
match_range => "1,2";
in_range_define => { 'httpd_stragglers' };
}
body process_select apache_user {
process_owner => { 'root', 'www', 'apache' };
process_result => "process_owner";
}
