Subject: Run mdev -s after modules are loaded
X-Git-Tag: v3.4.39~1
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=3ef477862d08c20628273c3c855bb78d6e417b25;p=genkernel.git

Run mdev -s after modules are loaded

Running `mdev -s` will ensure that device nodes are properly initialized.
It does not function as a netlink hotplug daemon. We must run it after
the modules are loaded to ensure that /dev/zfs has been created before
userland programs attempt to use it.
