vlastni spousteci rc skript

[Petr Macek]

Zdravim,

potrebuji vytvorit vlastni /usr/local/etc/rc.d script, pro spousteni 
flow collectoru. Je to soucast monitoringu Cacti. Kolektor je napsany v 
PHP. Skript musi spoustet a ukoncovat vice php kolektoru/skriptu. Dle 
nejakych navodu mam funkcni reseni, pri spusteni to ted vypada takto:

57939  -  Is        0:00.00 daemon: Cacti-flow_collector[57940] (daemon)
57940  -  S         0:00.08 /usr/local/bin/php 
/usr/local/share/cacti/plugins/flowview/service/flow-capture-freebsd
57942  -  S         0:00.13 /usr/local/bin/php -q 
/usr/local/share/cacti/plugins/flowview/flow_collector.php --listener-id=1

Mam ale problem s tim, ze vsechny procesy jsou spustene jako uzivatel 
root a to samozrejme nechci. Potrebuji je spustit jako uzivatel apache 
nebo cacti. Kdyz si ale zkusim s timhle hrat a pridat usera do 
command_args, tak se mi to cele rozbiji, protoze dany uzivatel nema 
prava pro zapis pidfile a output_file.

Mozna je moje reseni uplne spatne, ale na jine jsem neprisel. Nenajde se 
tu nejaka rada?
