Subject: Make sure and get all the multipath related modules.
X-Git-Tag: 003~34
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=323428ced555c588b978b9a7bb8c9f8ef9641ec1;p=thirdparty%2Fdracut.git

Make sure and get all the multipath related modules.

Install all modules that are any of:
- scsi device handler
- dm log handler
- dm path selector
- dm target

It would be nice if we could tell which log handlers and targets are
multipath related, but we really can't.
