34 $"Usage: $(basename $0) [-s|--sync] [-v|--verbose] [--silent]
35 [--] <vserver> <command> <args>*
37 <vserver> is the name of a vserver.
39 Possible commands are:
40 start [--nodeps] <start-vservers-opts>*
41 ... starts the specified vserver
42 stop [--nodeps] <start-vservers-opts>*
43 ... stops the specified vserver
44 restart ... restarts the specified vserver; this is the subsequent
45 execution of a synchronized 'stop' and a 'start'
46 condrestart ... restarts the vserver when it is running already
47 suexec <user> <shell-command> <args*>
48 ... executes a command as the specified user in the vserver
49 exec <shell-command> <args*>
50 ... executes a command as root in the vserver
51 enter ... executes the configured shell in the vserver
52 chkconfig <chkconfig-options*>
53 ... modifies the init-system; currently, only Red Hat's
54 chkconfig is supported
55 running ... succeeds iff the vserver is running
56 status ... gives out some human readable status information about
57 the vserver, and succeeds iff the vserver is running
60 ... builds a new vserver from scratch
66 ... installs package(s) in the vserver
68 apt-get,apt-config,apt-cache <apt-opts>*
69 ... execute the apt-* command for the given vserver
71 ... execute the rpm command for the given vserver
73 pkgmgmt externalize|internalize [-y]
74 ... externalize or internalize the package-management for the
75 given vserver. 'Externalize' means that package metadata
76 and management tools (apt-get,rpm) are living in the host,
77 while 'internalize' means that data and programs from the
81 ... unify the vserver with its reference vserver(s).
