>Description:
messages report drive as cd0 but in fstab must be mounted ad cd1.

from /var/log/messages:
Apr 20 07:23:52 dav /kernel: wdc1: unit 0 (atapi): <CD-524EA-B/1.0A>, removable, accel, ovlap, dma, iordis
Apr 20 07:23:52 dav /kernel: acd0: drive speed 4134KB/sec, 128KB cache
Apr 20 07:23:52 dav /kernel: acd0: supported read types: CD-R, CD-RW, CD-DA, packet track
Apr 20 07:23:52 dav /kernel: acd0: Audio: play, 256 volume levels

Apr 20 07:23:52 dav /kernel: Waiting 15 seconds for SCSI devices to settle
Apr 20 07:23:52 dav /kernel: changing root device to wd0s2a
Apr 20 07:23:52 dav /kernel: cd0 at ahc0 bus 0 target 5 lun 0
Apr 20 07:23:52 dav /kernel: cd0: <PIONEER DVD-ROM DVD-303 1.10> Removable CD-ROM SCSI-2 device 
Apr 20 07:23:52 dav /kernel: cd0: 10.000MB/s transfers (10.000MHz, offset 8)
Apr 20 07:23:52 dav /kernel: cd0: Attempt to query device size failed: NOT READY, Medium not present
Apr 20 07:23:52 dav /kernel: cd1 at ahc0 bus 0 target 6 lun 0
Apr 20 07:23:52 dav /kernel: cd1: <HP CD-Writer+ 9200 1.0c> Removable CD-ROM SCSI-4 device 
Apr 20 07:23:52 dav /kernel: cd1: 10.000MB/s transfers (10.000MHz, offset 15)
Apr 20 07:23:52 dav /kernel: cd1: Attempt to query device size failed: NOT READY, Medium not present

from /etc/fstab:
/dev/acd0c              /cdrom  cd9660  ro,noauto       0       0
/dev/cd1c               /cdrom1 cd9660  ro,noauto       0       0

With this fstab entry a DVD in the Pioneer DVD ROM drive is mounted
correctly. But I do not understand why the boot messages report this
as cd0 and it must be mounted as cd1. 

Also a 'sh MAKEDEV cd1' does not do anything. No error but also no new
device. I had to create it manually with mknod. 

Maybe the mixture of ATAPI and SCSI cdrom confuses the system.
The systems unit numbering is not reflected correctly in the messages.
>How-To-Repeat:
ATAPI CDROM + SCSI CDROM ?
