Martin Schwenke 7980a4cb44 Eventscripts - new function ctdb_check_args() 
Pass this "$@" to do common eventscript argument checking.

For regular use putting this in 00.ctdb would be enough.  However, for
developer testing it can be useful to call this in other eventscripts.
For example, 10.interfaces and 13.per_ip_routing currently check these
by hand.

README 

This directory contains run-time support scripts for CTDB.

Selected highlights:

  ctdb.init

    An initscript for starting ctdbd at boot time.

  events.d/

    Eventscripts.  See events.d/README for more details.

  functions

    Support functions, sourced by eventscripts and other scripts.

  interface_modify.sh

    Script to support add/remove IPs and other funky stuff.  Not sure
    why this is separate... but it certainly allows easy wrapping by
    flock.

  statd-callout

    rpc.statd high-availability callout to support lock migration on
    failover.

Notes:

* All of these scripts are written in POSIX Bourne shell.  Please
  avoid bash-isms, including the use of "local" variables (which are
  not available in POSIX shell).

* Do not use absolute paths for commands.  Unit tests attempt to
  replace many commands with stubs and can not do this if commands are
  specified with absolute paths.  The functions file controls $PATH so
  absolute paths should not be required.
