init-top中systemd-udevd什么作用？

[yangzhengbao]

/usr/share/initramfs-tools/scripts/init-top


#!/bin/sh -e

PREREQS="all_generic_ide blacklist"

prereqs() { echo "$PREREQS"; }

case "$1" in
prereqs)
prereqs
exit 0
;;
esac

echo > /sys/kernel/uevent_helper

/lib/systemd/systemd-udevd --daemon --resolve-names=never

udevadm trigger --action=add

# Leave udev running to process events that come in out-of-band (like USB
# connections)
