Subject: This patch re-adds the udev and hotplug2 initialization fixes originally present... 
X-Git-Tag: reboot~26703
X-Git-Url: http://git.openwrt.org/?p=openwrt%2Fopenwrt.git;a=commitdiff_plain;h=0b341be6c02166915856fe9951c3162a5f6c4af2;hp=c0f8fa8757b5acf1d1fc3ba0813f9fd8ce1d94db

This patch re-adds the udev and hotplug2 initialization fixes originally present in /init but was removed when some code was moved from /init to /etc/preinit in rev 10870. This adds udev initialization and only handles hotplug2 initialization when hotplug2 is present.
