Subject: add initqueue --env and "online" hook
X-Git-Tag: 018~64
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=6e3cc00f4882edbabea75945308f8ae7c353bf82;p=thirdparty%2Fdracut.git

add initqueue --env and "online" hook

The "online" hook runs whenever a network interface comes online (that
is, once it's actually up and configured).

The initqueue --env argument is used to set "$netif" to the name of the
newly-online network interface.
