can't change links in /dev
Hi folks, I currently have a link in /dev between hda, a dvd drive, and /dev/dvd: lrwxrwxrwx 1 root root 3 2006-12-26 17:24 /dev/dvd - hda I want to change the link so that it points to hdc, another dvd drive: ie /dev/dvd - hdc I am unable to make this change, except in the current session and this doesn't survive a reboot. ie: rm /dev/dvd ln -s /dev/hdc /dev/dvd reboot ls -l /dev/dvd lrwxrwxrwx 1 root root 3 2006-12-26 17:24 /dev/dvd - hda I have no idea why this happens. How is the link being restored on boot? From where? tia, b. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

How is the link being restored on boot? From where? ummm... what system? kernel etc? are you running udev? have you messsed with the udev rules to cause this link to be created this way?

How is the link being restored on boot? From where? You probably use udev, which generates device files and symlinks dynamically. Take a look at /etc/udev/rules.d/z25_persistent-cd.rules. regards Andreas Janssen -- Andreas Janssen [EMAIL PROTECTED] PGP-Key-ID: 0xDC801674 ICQ #17079270 Registered Linux User #267976 http://www.andreas-janssen.de/debian-tipps-sarge.html -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Yeah, this would seems to be the problem. The file doesn't exist. So it's either configured differently or not set up. I haven't been tinkering with this BTW. (Sarge with a 2.6 custom kernel) Here's the output of /etc/udev/rules.d/ and /etc/udev/: /etc/udev/rules.d$ ls -l lrwxrwxrwx 1 root root 20 2006-05-23 21:49 020_permissions.rules - ../permissions.rules lrwxrwxrwx 1 root root 19 2006-05-23 21:49 cd-aliases.rules - ../cd-aliases.rules lrwxrwxrwx 1 root root 13 2006-05-23 21:49 udev.rules - ../udev.rules lrwxrwxrwx 1 root root 12 2006-05-23 21:44 z_hal-plugdev.rules - ../hal.rules /etc/udev$ ls -l total 21 -rw-r--r-- 1 root root 683 2005-05-29 10:36 cd-aliases.rules -rw-r--r-- 1 root root 785 2005-05-29 10:36 cdsymlinks.conf -rw-r--r-- 1 root root 897 2005-05-29 10:36 compat-full.rules -rw-r--r-- 1 root root 913 2005-05-29 10:36 compat.rules -rw-r--r-- 1 root root 4621 2005-05-29 10:36 devfs.rules -rw-r--r-- 1 root root 398 2005-05-19 12:46 hal.rules -rw-r--r-- 1 root root 416 2005-05-29 10:36 links.conf -rw-r--r-- 1 root root 2198 2005-05-29 10:36 permissions.rules drwxr-xr-x 2 root root 1024 2006-05-23 21:49 rules.d drwxr-xr-x 2 root root 1024 2006-05-23 21:49 scripts -rw-r--r-- 1 root root 333 2005-05-29 10:36 simple-cd-aliases.rules -rw-r--r-- 1 root root 558 2005-05-29 10:36 udev.conf -rw-r--r-- 1 root root 2884 2005-05-29 10:36 udev.rules Many thanks for your help, b. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
