-
-<vserver> is the name of a vserver.
-
-Possible commands are:
- start [--rescue [--rescue-init]] [<rescue-cmd> <args>*]
- ... starts the specified vserver
- stop ... stops the specified vserver
- restart ... restarts the specified vserver; this is the subsequent
- execution of a synchronized 'stop' and a 'start'
- condrestart ... restarts the vserver when it is running already
- suexec <user> <shell-command> <args*>
- ... executes a command as the specified user in the vserver
- exec <shell-command> <args*>
- ... executes a command as root in the vserver
- enter ... executes the configured shell in the vserver
- chkconfig <chkconfig-options*>
- ... modifies the init-system; currently, only Red Hat's
- chkconfig is supported
- running ... succeeds iff the vserver is running
- status ... gives out some human readable status information about
- the vserver, and succeeds iff the vserver is running
-
- build <buildopts>*
- ... builds a new vserver from scratch
- delete ... remove a vserver
-
- unify [-R] <vunify-opts>*
- ... (de)unify the vserver with its reference vserver(s).
-
- pkg install <pkg>
- ... installs package(s) in the vserver
-
- apt-get,apt-config,apt-cache <apt-opts>*
- ... execute the apt-* command for the given vserver
- rpm <rpm-opts>*
- ... execute the rpm command for the given vserver
-
- pkgmgmt externalize|internalize [-y]
- ... externalize or internalize the package-management for the
- given vserver. 'Externalize' means that package metadata
- and management tools (apt-get,rpm) are living in the host,
- while 'internalize' means that data and programs from the
- vserver will be used.
-
- hashify
- ... hashify the guest.
