I'll assume that none of the links you're trying to make will cause problems or confusion. If they do, it's your problem, not mine.
Eg I want to make symlinks like /dev/modem -> /dev/ttyS0,
ln -s /dev/ttyS0 /dev/modem
/dev/dvdburner -> /dev/sr0

Does the kernel really call the device 'dvd1'? The KERNEL name is what the kernel calls the device, not the name you would like. You don't have much control over that name. It is probably whatever the /dev/ name is before you do anything. Maybe it is something like sr0? The SYMLIMK value is what you want your link called. It can be any legal name.

It is controlled by 60-cdrom_id.rules, which calls a program called cdrom_id, and 70-persistent-cd.rules contains the rules created by the write_cd_rules script.

The rules files are read alphabetically. Or, numerically, in fact. The number at the beginning controls the order the rules are added. If there is no last_rule directive, udev appends each appropriate rule in the order the rules files are read. So one need not modify this file as it contains no last_rule directives. Just add a rule that will be read in later that does what is wanted. In this case, the name of the rule file should be > 60. The trick here is finding what rules are consulted for each device. The udevmonitor program is nice for pluggable devices. I have never been able to find an easy human usable method to get the same info for static devices, like a built-in cd drive. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Kapellgränd 7 P.O.

Maybe there is a mtehod to tell the daemon to log things as they are done, but I don't know who calls the daemon: udevd - event managing daemon ... log_priority=value Set the internal log level of udevd. Valid values are the numerical syslog priorities or their textual representations: err, info and debug. Ah, it is "/etc/init.d/boot.udev". It uses: udevd_args="--daemon" so probably the way would be to modify that line in the script to add the log priority. - -- Cheers, Carlos E.

For me, the output of "udevtest /sys/block/sr0" (my built-on dvd writer) looks quite verbose. HTH Jan -- You can have peace or you can have freedom.

But part of the trick when debugging new rules is knowing that the name of the device in this context is /sys/block/sr0. This gets more interesting for pluggable devices. You have to know the name to find out about it. But where do you get a list of those udev-compatible complete device name in the first place? What is missing from udevtest's list is which name will be called, for example, KERNEL, when the rule is used. udevmonitor can be made to do this, but only for pluggable devices. Unless one changes daemon default startup parameters and reboots. A neat tool would be one that listed all the variables supplied to udev rules for all devices currently in the system. By combining a couple of programs and changing some system daemon options, perhaps with a boot or two added, the info can eventually be obtained. There has to be an easier way. -- Roger Oberholtzer OPQ Systems / Ramböll RST Ramböll Sverige AB Kapellgränd 7 P.O.

Thanks Robert, I was thinking something similar but was afraid that my rule would interfere with the systems own rules. And I did not know 'last_rule' option. I will give a try.
