New Revision: 1380
Added:
branches/cman-based/vendor/common/o2cb.init.in
Removed:
branches/cman-based/vendor/common/o2cb.init
Modified:
branches/cman-based/configure.in
Log:
o2cb.init now knows how to configure the backing cluster stack. It can
start the drivers regardless of whether o2cb, heartbeat2, or cman is the
backend.
Move o2cb.init to o2cb.init.in. This allows us to propagate
BUILD_CMAN_SUPPORT to the init script.

-# This is a tricky bit of eval work. There are many steps involved in

-# follows:
-#
-# start/load:
-# Eval of the exact lines, in order. So, the first call is
-# "eval load_module configfs".
-#
-# status:
-# Eval of the lines with "check_" prepended, in order. So the first
-# call is "eval check_load_module configfs".
-#
-# stop/unload:
-# Eval of the lines with "un" prepened, in reverse order. So the
-# *last* call is "eval unload_module configfs".
-#
-# To provide an action, create a set of shell functions or commands
-# "foo", "check_foo", and "unfoo". Then add "foo arguments" to the
-# appropriate place. Be careful, eval requires quoting to be right.
