Subject: [PATCH] Add a check file for multipath.
|
|
Date: Fri, 22 Jan 2010 10:56:40 -0500
|
|
|
|
If multipath isn't installed, don't use it. If we're in hostonly mode,
|
|
only install the multipath module if it's used for / . Otherwise, if
|
|
the user was dumb enough to install it, they get it during bootup.
