Warm Greetings To users at dragonflybsd.org,

Almost exactly one (1) year ago today, this same topic -- DragonFlyBSD 
on ISO -- was discussed on users at dragonflybsd.org

Please refer to my earlier message:
   Subject: Re: Booting problem
   Date: August 18, 2015

Here is a paste of the complete text of that message:

==================
I agree with Stephen Walker and Gennady Proskurin,

Please don't drop generation of DragonFlyBSD ISO images.

I am using DragonFlyBSD as a KVM guest os on Elastic Hosts (EH)
www.elastichosts.com. EH supports custom os install for KVM by means of 
ISO
image.

Hi,

Please don’t retire ISO generation.

I only (clean) install production distributions from CD (ISO).

I realize that the more "hardcore" DragonFlyBSD community members are 
booting DragonFlyBSD straight on to bare metal servers. In this case, a 
USB memory stick is no doubt very fast and convenient way to install / 
boot the OS.

However, as I have argued in more than one posting to this forum, the 
DragonFlyBSD OS has great potential to make inroads as a great OS for 
use under QEMU / KVM virtualization. The economics of QEMU / KVM are 
compelling, as this virtualization standard has brought about a 
quasi-commodifed highly competitive VPS market, to the great economic 
advantage of website builders.

In my case, I cannot justify the cost of a dedicated server machine. So 
if I cannot use DragonFlyBSD on a QEMU / KVM VPS, then I cannot use 
DragonFlyBSD.

Recently the DragonFlyBSD team put considerable effort into helping one 
DragonFlyBSD user, Stefan Unterweger 232.20711 at chiffre.aleturo.com, to 
get his DragonFlyBSD application working under QEMU / KVM 
virtualization. I have been very encouraged to see this broad-minded 
attitude among DragonFlyBSD developers, who have helped Stefan by 
working quickly to fix problems with DragonFlyBSD (e.g. virtio support).

I just now checked the www.elastichosts.com (EH) website, and it appears 
that for EH VPS offerings, there is still only one way to install a 
custom guest OS under an EH VPS, and that is means of ISO image.

So once again, here is a plea from a QEMU / KVM user who wants to use 
the fantastically amazing DragonFlyBSD OS (and its kick-ass Hammer 
filesystem) under QEMU / KVM virtualization at EH. But if DragonFlyBSD 
developers drop production of ISO-formatted releases, they will just be 
adding another barrier holding back potential market growth for 
DragonFlyBSD.

Best Regards,

Steve

Is the floppy drive related stuff still needed ???
