Hi Pierre,

Here’s what you have to do to install dfly 4.4 on DigitalOcean:

1. Create a FreeBSD droplet and login to it
2. fetch http://mirror-master.dragonflybsd.org/iso-images/dfly-x86_64-4.4.1_REL.img.bz2
3. bunzip2 dfly-x86_64-4.4.1_REL.img.bz2
4. sudo swapoff /dev/gpt/swapfs
5. sudo sysctl kern.geom.debugflags=0x10
6. sudo dd if=dfly-x86_64-4.4.1_REL.img of=/dev/vtbd0 bs=512k
7. At this point, shutdown /  reboot commands probably no longer work so just go ahead and power cycle the droplet
8. When asked, boot from ufs:vbd0s1a
9. login as root in order to have a shell
10. use fdisk to create a 2nd slice (the first slice is a 2G one created when you dd'ed the usb image into the disk)
11. exit the shell and login as installer
12. install dfly into the 2nd slice.

With this setup you lose the first 2GB to the installer slice but it could also be handy as an emergency slice.
