Apparently, all I needed to do was to edit /etc/fstab and replace
scd with sr

before:

/dev/scd0       /media/cdrom1   udf,iso9660 ro,user,noauto  0       0
/dev/scd1       /media/cdrom2   udf,iso9660 ro,user,noauto  0       0

after:

/dev/sr0       /media/cdrom1   udf,iso9660 ro,user,noauto  0       0
/dev/sr1       /media/cdrom2   udf,iso9660 ro,user,noauto  0       0

The installer setup my fstab incorrectly.
