[Bug 1093731] [NEW] udev-finish.conf fails to merge temporary rules files

[Yutani]

Public bug reported:

I removed /etc/udev/rules.d/70-persistent-net.rules and rebooted the machine in order to generate a new rules file, but couldn't get a complete 70-persistent-net.rules. A rule about eth0 was written in /run/udev/tmp--70-persitent-net.rules and didn't merged onto /etc/udev/rules.d/70-persistent-net.rules, which udev-finish.conf is 
expected to do.

This is probably because the tmp dir path specified in udev-finish.conf
is different from that in /lib/udev/rule_generator.functions.


/lib/udev/rule_generator.functions:
        RUNDIR=$(udevadm info --run)
        local tmp_rules_file="$RUNDIR/tmp-rules--${RULES_FILE##*/}"


/etc/init/udev-finish.conf:
    # Copy any rules generated while the root filesystem was read-only
    for file in /dev/.udev/tmp-rules--*
    do
        [ -e "$file" ] || continue
        cat "$file" >> "/etc/udev/rules.d/${file##*tmp-rules--}"

		
In my environment, "udevadm info --run" returns "/run/udev". I think udev-finish.conf should use $(udevadm info --run) instead of "/dev/.udev/".
