lucid: cdrom entry is missing in /etc/fstab

[Alvin]

Binary package hint: debian-installer

Since Lucid, the cdrom entry in /etc/fstab is missing. Upgrades retain this entry and do not have this problem.

Solution after installation: add the entry in /etc/fstab if a cdrom is present and create the /media/cdrom0 directory and /media/cdrom link

Example in /etc/fstab:
/dev/scd0 /media/cdrom0 udf,iso9660 user,noauto,exec,utf8 0 0

It was removed intentionally - putting it in /etc/fstab is no longer a
sensible thing to do on a distribution-wide basis in these days of
dynamic device handling. Does something break for you because cdrom is
no longer in /etc/fstab? If so, what?

[Alvin (alvind)]

I'm used to mounting a cdrom like this:
~$ mount /dev/cdrom
mount: can't find /dev/cdrom in /etc/fstab or /etc/mtab

Is there a new method I don't know about?

[Alvin (alvind)]

Any news on how cdroms are mounted nowadays?

Thank you for taking the time to report this bug and helping to make Ubuntu better. In an effort to keep an up-to-date list of bugs to work I have reviewed this report to verify it still requires a fix and it occurs on a supported version of Ubuntu.

As stated above the removal was done intentionally. If you still wish to mount a cdrom device the typically suggested way of doing this is 1) add it manually to fstab, as originally posted by the submitter or 2) as follows:

sudo mkdir -p /mnt/cdrom
mount /dev/cdrom /mnt/cdrom

It is unfortunate that we were unable to resolve this defect, however there appears to be no further action possible at this time. I am therefore moving the bug to 'Invalid'. If you disagree or have additional details, please feel free to add a comment and then change the status of the bug to 'New'.
