mdev: do not complain if mdev.conf does not exist;
use #if to prevent gcc from generating dead code
(sadly, it's more ugly this way)

create your own total match like so:

-You can rename/relocate device nodes by using the next optional field.
- <device regex> <uid>:<gid> <octal permissions> [>path]
+You can rename/move device nodes by using the next optional field.
+ <device regex> <uid>:<gid> <octal permissions> [=path]
So if you want to place the device node into a subdirectory, make sure the path
has a trailing /. If you want to rename the device node, just place the name.
- hda 0:3 660 >drives/
-This will relocate "hda" into the drives/ subdirectory.
- hdb 0:3 660 >cdrom
+ hda 0:3 660 =drives/
+This will move "hda" into the drives/ subdirectory.
+ hdb 0:3 660 =cdrom
This will rename "hdb" to "cdrom".
+Similarly, ">path" renames/moves the device but it also creates
+a direct symlink /dev/DEVNAME to the renamed/moved device.
+
If you also enable support for executing your own commands, then the file has
the format:
- <device regex> <uid>:<gid> <octal permissions> [<@|$|*> <command>]
+ <device regex> <uid>:<gid> <octal permissions> [=path] [@|$|*<command>]
+ or
+ <device regex> <uid>:<gid> <octal permissions> [>path] [@|$|*<command>]
The special characters have the meaning:
@ Run after creating the device.
$ Run before removing the device.
