cgrulesengd: control group rules daemon


cgrulesengd - control group rules daemon


cgrulesengd [options]


cgrulesengd is a daemon, which distributes processes to control groups. When any process changes its effective UID or GID, cgrulesengd inspects the list of rules loaded from the cgrules.conf file and moves the process to the appropriate control group.

The list of rules is read during the daemon startup is are cached in the daemon's memory. The daemon reloads the list of rules when it receives SIGUSR2 signal. The daemon reloads the list of templates when it receives SIGUSR1 signal.

The daemon opens a standard unix socket to receive 'sticky' requests from cgexec.

-u <user>|--socket-user=<user>
