The +/run mountpoint is supposed to be a tmpfs mounted during early boot, +available and writable to for all tools at any time during bootup, +it replaces /var/run/, which should become a symlink some day. + +If /run does not exist, or is not writable, udev will fall back using +/dev/.udev/. + +On systemd systems with initramfs and LVM used, packagers must +make sure, that the systemd and initramfs versions match.

With devtmpfs +udev passed control over device nodes to the kernel. This option +should not be needed, or can not work as advertised. Neither +udev nor the kernel will remove device nodes which are copied from +the /lib/udev/devices/ directory. All "add|change" matches are replaced by "!remove" in the rules and in the udev logic.
