[cobbler] cobbler managing debian install no CD-ROM detected

[Tony Schreiner]

Have been managing CentOS system with cobbler for a while, and decided to
try to add Debian to the mix.

I loop mounted the firmware-8.4.0-amd64-netinst.iso image, which is current
Jessie netinst + non-free firmware, and ran import as

# cobbler import --name=jessie --breed=debian --os-version=jessie
--path=/mnt

*** TASK COMPLETE ***

looks pretty normal.
I have created a sub-profile based on jessie-x86_64 called
jessie-precision670 (old dell workstation), but the only difference is the
assignment of preseed file slightly modified from sample.seed as the
kickstart. Then I assigned this profile to a system.

When the system installs, during the hardware discovery, it shows:

No common CD-ROM drive was detected.

...

and I cannot proceed. This seems to be before network detection takes place.
I first tried with the regular debian-8.4.0-amd64.iso image; the network
driver is e1000.

Any suggestions?
