I think you are talking about a script that handles a more dynamic database to force renames/softlinks for devices keeping names identical? I haven't played with mdev yet, but isn't that already in mdev? Or does mdev require it to be set manually? Well, to make mdev simple enough for embedded devices (whose devices always come up in the same order), busybox devs do not include any database of devices. However, mdev is perfectly able to execute a program (script or binary) when it detects a device coming up, and it can choose which program to execute based on the device name. Let's say you have two NICs, one will get eth0, the other will get eth1, depending on the order that the kernel initializes the device name. For that, you don't have to do a thing. However, if the devices somehow gets initialized at the same time (e.g., hotplug events), it's a toss which dev will get which name. That is why, the busybox devs recommended the linuxrc file to contain the line mdev -s, which will handle dev initializations during boot in a sequential fashion, ensuring exact same device names. Btw, the keep same devicename is rather annoying when having to replace the network card and the network then doesn't come back up... There are several scenarios: Scenario 1: eth1 is replaced, eth0 stays -- if the new card is initialized after eth0, it will automatically assume eth1. If the new card is initialized before eth0, it will become the new eth0, and the previous eth0 will become eth1 automatically. Scenario 2: eth0 is replaced, eth1 stays -- if the new card is initialized before eth1, it will automatically assume eth0. If the new card is initialized after eth1, the previous eth1 gets eth0, while the new card gets eth1. The program (script) I'm planning will have a simple 'database' (actually, a text file) containing pairs of MAC address and devname. This should ensure that devices with a certain MAC address will *always* get the same devname, while devices not listed in the database will get the first available devname. Thus, in the case where devname swapping would happen (see the second situation in Scenarios 1 2), *at least* the non-replaced device will get the exact devname as before replacement happens.

Hi, Gentoo. Yes, I've got Gnome going under mdev. Thanks to Mike Edenfield for the tip about needing to configure things in xorg.conf. Here's how I did it: (i) Rebuild xorg-server without udev. * Insert this line into /etc/package.use: x11-base/xorg-server -udev * build the program with: emerge xorg-server (ii) Configure the keyboard and mouse explicitly in /etc/X11/xorg.conf (or wherever else you keep your xorg.conf). * Edit the two InputDevice sections to look like this. The critical lines are emphasised: Section InputDevice Identifier Keyboard0 Driver evdev -- Option Device /dev/input/event3 -- EndSection Section InputDevice Identifier Mouse0 Driver evdev -- Option Protocol auto Option Device /dev/input/event4 -- Option ZAxisMapping 4 5 6 7 EndSection Here's another section for your instructions, Walter. :-) -- Alan Mackenzie (Nuremberg, Germany).
