#!/sbin/openrc-run

# If you want to run separate master process per pool, then create a symlink
# to this runscript for each pool. In that mode, the php-fpm daemon is started
# as nobody by default. You can override the user (and group) by declaring
# variable "user" and optionally "group" in conf.d file, or in the $fpm_config
# file (the former has precedence).
