 |
|
| I recently updated via emerge world -u. Now, I have no /dev/dvd. I am running udev-062 and gentoo-sources-2.6.12-r4. Worked before, but doesn't now. Any ideas? |

With both udev and devfs, /dev/dvd is just a link to the actual device at /dev/ide/<something>. For instance, if I do a `ls -l /dev/dvd` on my box, i get:
| Code: | bitbucket proc # ls -l /dev/dvd
lr-xr-xr-x 1 root root 35 Jun 1 02:21 /dev/dvd -> /dev/ide/host0/bus1/target1/lun0/cd |
Look around in the /dev/ide directory and see if you can figure it out. If not, have a look in the /proc/ide directory. Each drive in this directory has a "model" file that can be used to determine which device is which. Once you know which /dev/ide/* device is your dvd drive, you can create a link by doing this:
| Code: | | ln -s /dev/ide/host0/bus1/target1/lun0/cd /dev/dvd |
...of course, you shoudn't use that exact command unless your dvd drive is at the same host/bus/target/lun location as mine.
Good luck!

Thanks for the reply. Looks like I got the symlink back by uncommenting out a line in /etc/udev/cdsymlinks.conf. That config file is new to me. I have a symlink, /dev/dvd, pointing to /dev/hdc. The permissions on /dev/hdc are root:root 660. They should be root:cdrom 660 according to my udev permissions file. I don't get it.
Damned udev. |

Afaik udev doesn't use the permissions file anymore in newer versions.
It all depends on the rules...
