iso file size after decompression, overburning

Fri Aug 19 13:45:48 PDT 2016

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 it time to scrap the relics that's called games ???
Is the floppy drive related stuff still needed ???
