What am I doing wrong? low level: You're creating the link on a tmpfs. This is by definition gone by a reboot. high level: You're not using udev's means to create (symbolic) links for devices, which you should. Add a rule that does this for you... BTW: Why isn't gentoo creating this link automatically for you? usually 50-udev.rules cares for that by calling /lib/udev/cdrom_id. If that program doesn't recognize your DVD drive, you might certainly file a bug... -hwh -- [EMAIL PROTECTED] mailing list

/dev does not exist on a disk, it is created on the fly by udev, so any
hard links you make are never written to persistent storage
You will need to create a udev rule for this
Something like:
# cdrom symlinks and other good cdrom naming
KERNEL==sr[0-9]*|hd[a-z]|pcd[0-9]*, ACTION==add,
IMPORT{program}=cdrom_id --export $tempnode
ENV{ID_CDROM}==?*, GROUP=cdrom
# assign cdrom-permission also to associated generic device (for
cd-burning ...)
KERNEL==sg[0-9]*, ACTION==add, ATTRS{type}==4|5, GROUP=cdrom
in /etc/udev/rules.d/50-udev.rules
...and read http://www.reactivated.net/writing_udev_rules.html for the
details.
Bye...

It should be already there, shouldn't it?
In that case, probably /lib/udev/cdrom_id doesn't catch it, so just
adding the above lines another time won't help. Of course, a simple
rule like
KERNEL==sg0, SYMLINK=dvd
should be enough. And you certainly shouldn't edit distribution
provided udev rules w/o good reason, but rather create a new rules file
below /etc/udev/rules.d (so that further distribution updates of udev
don't require you to merge config files).
