Subject: Add some predefined break points.
X-Git-Tag: 0.1~414
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=8177ca3e1e702a48c688adfac9916ebad934c8e2;p=thirdparty%2Fdracut.git

Add some predefined break points.

We now have a breakpoint just before each of the hook invocations, and one
just before we switch to the real root.
