Subject: 95iscsi: Fix network setup code for iscsi
X-Git-Tag: 050~201
X-Git-Url: http://git.ipfire.org/?p=thirdparty%2Fdracut.git;a=commitdiff_plain;h=7b76fa924dfd20d3fd4433baa8292f0112282aac

95iscsi: Fix network setup code for iscsi

- The network script and config could be in
  "/etc/sysconfig/network-scripts", so try look for network config in
  all possible path.

- The regex used for sed is not working, so fix it too.

- Make bootproto a local variable
