[gentoo-user] fstab and cdrom question

[Denis]

Hello folks,

Quick question.

My main HD is SATA and gets /dev/sda in fstab.  My CDROM, which is the
only device on the IDE bus, seems to be /dev/hda.  That's what
Audacious declared when it was looking for a CD to play.  I had CDROM
device forced to /dev/cdrom in Audacious, unwittingly, before and was
wondering why my CDs were not playing!  However, my fstab is still
"/dev/cdrom              /mnt/cdrom      auto            noauto,user
  0 0" - so should I switch this to /dev/hda instead of /dev/cdrom?
If so, should some link be made to /dev/cdrom, if other programs may
be querying /dev/cdrom for the sake of Linux standard convention, or
is /dev/cdrom already a link, which was broken in my case?

Thank you,
Denis

Sure, if you like.

The default udev scripts should have been able to automatically create
symlinks for optical devices in /dev. Whether yours is broken, you can
find out by trying to ls -l /dev/cdrom :)

It appears the links /dev/cdrom1 and /dev/cdrw1 are tied to /dev/hda.
Is that the default behavior instead of /dev/cdrom now?

Take a look at /etc/udev/rules.d/70-persisten-cd.rules, which may
be pointing to the wrong hardware.  Just delete that file and udev
will create it again on the next boot.

That's what I have on my machines, except that I have /dev/cdrom instead of
cdrom1.  Do you have more than one cd device?  If not, you should delete
/etc/udev/rules/70-persistent-cd.rules and reboot.

You don't need an fstab entry at all.  These days, when you insert a CD, 
it will get mounted automatically and appear in /media, just like USB 
storage devices.

I'm on the train so its hard to check the man pages but can't you use
udevtrigger or a similar tool so rebooting isn't required?
